How do you read Blast Motion app data?

Reading Blast Motion app data comes down to three layers. First, the Swing Quality Scores — the Plane, Connection, and Rotation (PCR) grades on the 20-80 scouting scale, calibrated to the athlete's level of play, which tell you how good the swing was relative to peers. Second, the raw metrics like bat speed in mph, on-plane efficiency as a percentage, and early connection in degrees, which tell you exactly what the swing did. Third, the Blast iQ green-yellow-red colors that prioritize the one metric to fix next. Start with the score to spot the problem, open the metric to measure it, then act on the red. One red metric, one matched drill, one week.

What is the difference between Blast Motion scores and metrics?

Scores and metrics are two different layers of the Blast app that answer two different questions. Swing Quality Scores are the Plane, Connection, and Rotation (PCR) grades on the 20-80 baseball scouting scale, calibrated to the athlete's level — a 50 is average for your level, 60+ is above average, 70+ is elite. They tell you how good the swing was relative to peers. Raw metrics are the measurements themselves: bat speed in mph, on-plane efficiency as a percentage, early connection in degrees. They tell you exactly what the swing did. The scores live on the swing summary. Tap into a swing to see the underlying metrics that produced each score.

What do the Blast iQ green, yellow, and red colors mean?

Blast iQ color-codes each swing metric with a traffic-light system. Green means the metric sits in the target range for that athlete's level — leave it alone. Yellow means the metric is drifting outside the target range — monitor it across the session. Red means the metric is off target and costing the athlete — this is the focus area. Work one red at a time. If bat speed and connection both flag red, pick the one that drives the bigger outcome for the athlete's level and drill that. Chasing every red simultaneously scatters reps and stalls progress. The correct protocol is one red metric, one matched drill, one week, then retest.

What are the target ranges for key Blast Motion metrics?

Core baseball metric targets: Bat Speed by level — Pro 66-78 mph, HS Varsity 60-70 mph, Middle School 46-62 mph. On-Plane Efficiency 70%+ (MLB baseball average 68.6%). Early Connection target 90 degrees inside an 80-105 degree range. Attack Angle productive around 6-14 degrees — treat this as directional rather than exact since a 2022 peer-reviewed study found swing-angle metrics are less precise than bat-speed readings on knob-mounted sensors. Rotational Acceleration: higher is better — it is the 0-60 time of the swing and is where raw bat speed becomes game power. For softball, bat speed targets differ by level: use Blast's fastpitch database benchmarks, not baseball numbers.

Should I read one swing or a full session of Blast Motion data?

Always read a full session trend, never a single swing. One swing lies — a session average tells the truth. Ten swings show your real average and your consistency, which is what actually plays in games. Blast benchmarks every reading against 400M+ captured swings for level-specific context, so averages are meaningful while single readings can be outliers. Look at the spread as well as the average: a hitter averaging 68 mph with a tight range is more game-ready than one who spikes to 72 mph once and sits at 60 mph the rest of the round. Do not rebuild a swing based on one bad rep. Do not validate a swing based on one good rep. Judge progress on the trend line.

Which drill should I run for each Blast Motion red metric?

Match each flagged metric to its correct drill. Low bat speed from poor hip-shoulder separation: Torque Drill plus Knob to Knee Drill — trains hips to lead the shoulders. Do not use the Dead Legs Drill for this. Over-rotation, pulling off the ball, or Early Extension: Dead Legs Drill — isolates the upper body. Casting (barrel leaking away from the body): Stop at Contact Drill with the cue 'Short to it, long through it.' Weak or inconsistent forward move or Sway: Walk Through Drill with the cue 'Land firm, turn behind your front hip.' Poor hip-shoulder separation generally: Shoulder Slot Drill or Torque Drill matched to the specific flagged dimension. Use 'Back pocket down the line' to feel the pelvis load on any rotational work. Run the matched drill for one week, then retest that metric specifically.

How is reading Blast Motion data different for softball versus baseball?

Softball bat speed targets are lower than baseball at every level because of shorter bats, lighter barrels, and a different swing timing window — never compare a softball number to a baseball benchmark. Blast Softball benchmarks from the fastpitch database: Recreational 32-46 mph, Travel 12U-14U 38-52 mph, HS JV 42-56 mph, HS Varsity 49-63 mph, Travel 16U-18U 54-66 mph, College 58-70 mph, Professional 63-75 mph. Track Bat Speed, Hand Speed, and Power together over time. The Blast iQ color system and 20-80 score calibration both adjust automatically to the sport and level you set in the app — set it correctly before reading any output.

How accurate is Blast Motion data?

A peer-reviewed 2022 study in the journal Sports tested knob-mounted bat sensors including Blast against optical motion capture and found bat speed tracks reliably (mean ICC of 0.78) but swing-angle metrics are less precise (mean ICC of 0.58), with accuracy declining at very high swing speeds. Blast also promotes a 2016 internal comparison showing a 3 mph standard deviation for bat speed versus 5 mph and 7 mph for two competitors — treat this as vendor data rather than independent proof since it was not peer-reviewed. The practical takeaway: trust bat speed as a reliable training signal for tracking trend improvements session over session. Treat Attack Angle and other angle metrics as directional trends rather than certified measurements, and always use one method consistently so you are comparing the same measurement to itself.

How to Read Blast Motion App Data Like a Coach

August 21, 2026
Andrew Don

Your athlete finishes a cage session, opens the Blast app, and stares at a wall of numbers. Bat speed, on-plane efficiency, connection, a stack of colors. Learning how to read Blast Motion app data turns that clutter into a plan.

Reading your Blast data comes down to three layers.

First, the Swing Quality Scores (Plane, Connection, Rotation) on the 20 to 80 scale.
Second, the raw swing and impact metrics like bat speed and attack angle.
Third, the green, yellow, and red Blast iQ colors that flag the one thing to fix next.

Master those three, and every session gives you a direction.

1. Start With the Screen: Scores vs. Metrics

A parent holds up the app and asks, “Is a 55 good?” without knowing whether that is a score or a metric. That mix-up is the first thing to fix.

Blast shows two different kinds of numbers, and they answer two different questions.

Swing Quality Scores are the Plane, Connection, and Rotation (PCR) grades. Blast iQ scores each on the 20 to 80 scouting scale, calibrated to the athlete’s level of play. They tell you how good the swing was relative to peers.
Raw metrics are the measurements themselves: Bat Speed in mph, On-Plane Efficiency as a percentage, Early Connection in degrees. They tell you exactly what the swing did.

Scores live on the swing summary as a quick read. Tap into a swing to see the underlying metrics behind each score. When you learn how to read Blast Motion app data, always ask which layer you are looking at before you react. Start with the score to spot the problem, then open the metric to measure it.

2. The Green, Yellow, and Red Colors, Decoded

A hitter sees three reds and panics, then chases all three at once and fixes none. The colors exist to stop exactly that.

Blast iQ color-codes each swing so you know where to look first:

Green means the metric sits in your target range. Leave it alone.
Yellow means it is drifting. Monitor it across the session.
Red means it is off target and costing you. This is your focus area.

Work the red first, and only one red at a time. If bat speed and connection both flag red, pick the one that drives the bigger outcome for your athlete’s level and drill that. Chasing every color at once scatters your reps and stalls progress. One red, one drill, one week.

3. The Core Swing Metrics and What “Good” Looks Like

A varsity hitter barrels balls in the cage but pops them up in games. The metrics tell you why. Here is what each core number means and the target to hold.

Bat Speed: the barrel’s speed through the zone. Baseball targets by level: Pro 66 to 78 mph, HS Varsity 60 to 70 mph, Middle School 46 to 62 mph.
On-Plane Efficiency: how long your barrel stays on the pitch plane. Aim for 70% or higher; the MLB baseball average is 68.6%. Learn more in what On-Plane Efficiency measures.
Early Connection: the body-to-bat angle at the Transition Event. Target 90 degrees, inside an 80 to 105 degree range.
Attack Angle: the vertical angle of the bat at impact, productive around 6 to 14 degrees. See how attack angle works.
Rotational Acceleration: the “0 to 60 time” of the swing. A high RA is what turns a fast bat into game power.
Time to Contact: how quickly you get the barrel to the ball, in seconds.

Keep Connection and hip-shoulder separation separate. Connection is the body-to-bat relationship; hip-shoulder separation is the X-Factor that loads rotational power. One honest caveat on precision: a peer-reviewed 2022 study in the journal Sports found knob-mounted bat sensors track bat speed reliably (mean ICC 0.78) but read swing angles less precisely (mean ICC 0.58), and bat-speed accuracy can slip at very high swing speeds. Treat Attack Angle as directional, not exact, and trust the trend.

4. Reading Blast Softball and Blast Golf Data

A 16U travel hitter and a middle school hitter should never chase the same speed, and neither should borrow a baseball number. These Blast Softball benchmarks, drawn from Blast’s swing database of fastpitch hitters, stand on their own:

Recreational: 32 to 46 mph
Travel 12U to 14U: 38 to 52 mph
HS JV: 42 to 56 mph
HS Varsity: 49 to 63 mph
Travel 16U to 18U: 54 to 66 mph
College: 58 to 70 mph
Professional: 63 to 75 mph

Set the target to your athlete’s level, then track Bat Speed, Hand Speed, and Power over time. Blast Softball is the official partner of USA Softball and the USA Softball Women’s National Team.

Golf reads entirely differently. Blast Golf tracks club speed, tempo, face rotation, attack angle, hand speed, and detailed putting metrics for speed and direction. On the full swing, Blast Golf’s tour tempo range runs 2.5:1 to 3.1:1, meaning the backswing takes roughly three times as long as the downswing. Blast iQ uses traffic-light goal ranges benchmarked by your handicap and club type, and 200+ Tour professionals rely on it. Never read a golf number against a bat-speed table.

5. Read a Set of Swings, Not One

An athlete takes one bad rip, sees a red, and rebuilds a swing that was fine yesterday. One swing lies. A set of swings tells the truth.

Read the trend across a full session or round, not a single rep. Ten swings show you your real average and your consistency, which is what actually plays in games. Blast benchmarks every reading against a database of 400M+ captured swings, so your averages get compared to level-specific targets, not a generic standard.

Look at the spread, too. A hitter averaging 68 mph with a tight range is more game-ready than one who spikes to 72 mph once and sits at 60 mph the rest of the round. For baseball and softball athletes who also want an AI-video layer on top of the sensor, WIN Reality’s SwingAI pairs well as the vision-based complement. Judge progress on the trend line, not the outlier.

6. Turn Your Numbers Into the Next Drill

A red metric is only useful if it points to a fix. Match the flagged metric to the right drill instead of guessing.

Low bat speed from poor hip-shoulder separation: run the Torque Drill plus the Knob to Knee Drill to train the hips to lead the shoulders. Do not reach for the Dead Legs Drill here.
Over-rotation, pulling off the ball, or Early Extension: the Dead Legs Drill isolates the upper body for exactly these, not for building bat speed through separation.
Casting, where the barrel leaks away from the body: the Stop at Contact Drill. Cue it with “Short to it, long through it.”
Weak or inconsistent forward move, or Sway: the Walk Through Drill. Coach it with “Land firm, turn behind your front hip.”
Poor hip-shoulder separation generally: the Shoulder Slot Drill or Torque Drill, matched to the flagged dimension.

Use “Back pocket down the line” to feel the pelvis load on rotational work. Keep mind and mechanics together: an athlete thinking about mechanics mid-swing usually breaks down, so drill the fix in practice, then compete free. Run the matched drill for a week, then let the sensor confirm the change.
