Brent Pourciau's Analysis
Road to 90
Personalized roadmap for Jackson Miller
The Overview
Alright Jackson, here's your Road to 90. You're currently sitting at 73 mph, which means you need about 17.0 mph to hit your target of 90. Your profile is in the 45th percentile overall, which means there's significant room to grow. The good news? Every improvement you make will translate to velocity.
What The AI Analysis Tells Me
Jackson, here's your reality check. You're at 73 mph, and the AI model predicted 74.8 mph based on your physical profile. You're pretty much right where you'd expect to be. This means you're efficiently converting your athleticism into velocity — no major mechanical leaks, but also room to grow both physically AND mechanically.
Your mechanics efficiency is at the 32th percentile — there's definitely room to improve here. This isn't bad news, though. It means that as we work on your movement patterns and delivery, you'll see velocity gains without even getting stronger. The 3X Pitching Velocity Program addresses exactly this.
Your Biggest Opportunities
Based on the AI analysis, here are your biggest opportunities to add velocity:
Broad Jump
+2.1 mph
Current: 90.0" (26th %ile)
→
Target: 98.0" (56th %ile)
Why it matters: Your broad jump is one of the best predictors of pitching velocity because it measures your ability to produce horizontal force — exactly what you need off the mound.
How we fix it: The Stride Excelerator is perfect for this — it trains the exact horizontal force production pattern you use in your delivery. Combine that with plyometrics, bounds, and the TopVelocity Sled for resisted stride work.
Lateral Broad Jump
+2.0 mph
Current: 152.0" (38th %ile)
→
Target: 162.0" (68th %ile)
Why it matters: This measures your lateral power — critical because pitching involves a massive lateral push off the rubber before you rotate.
How we fix it: The Stride Excelerator trains this lateral drive pattern specifically. Combine it with lateral bounds and the TopVelocity Sled for lateral resisted work.
Vertical Jump 225
+1.8 mph
Current: 19.0" (41th %ile)
→
Target: 22.0" (71th %ile)
Why it matters: This metric has a direct correlation to pitching velocity based on our data from over 800 athletes.
How we fix it: The 3X Pitching Velocity Program includes specific protocols to target this. Combined with the TopVelocity training devices, you'll see improvement quickly.
These three priorities alone = +5.9 mph potential
The Mechanical Side
The AI also identified some mechanical variables from your motion capture data. There's about +6.1 mph worth of mechanical improvements available. These are things like trunk rotation speed, pelvis rotation, and arm timing — exactly what the 3X Pitching Velocity Program is designed to fix. The Trunk Excelerator specifically trains that rotational sequencing, and the Stride Excelerator grooves the lower half mechanics. This is where the real velocity unlocks.
Can You Hit Your Target?
Here's the best part — the math works. You need +17.0 mph to hit 90, and the improvements above give you +20.0 mph of potential. This is achievable. It's not going to happen overnight, but if you commit to the training and stay consistent, 90 mph is absolutely in reach.
My Recommendation
Based on everything I'm seeing here, here's what I recommend: The 3X Pitching Velocity Program is exactly what you need. This isn't just a throwing program — it's a complete system that addresses mechanics, strength, power, and motor learning all in one. Your mechanics efficiency score tells me there's velocity sitting on the table right now. The 3X Program will teach you how to sequence your body properly and transfer all that force into the ball. To accelerate your results, I highly recommend using the TopVelocity training devices that are built into the program: The Trunk Excelerator teaches you to generate and transfer rotational power through your core — this is where velocity lives. The Stride Excelerator builds explosive leg drive and proper stride mechanics, which is the foundation of the 3X approach. The Impulse Ground Force Trainer develops your ability to create force into the ground, and the TopVelocity Sled builds the specific strength patterns you need for a powerful delivery. These aren't gimmicks — they're tools designed to train the exact movement patterns that separate high-velocity pitchers from everyone else. Combine them with the 3X Program and you'll see results faster than training alone.
Your Top Physical Priorities
The two biggest physical drivers for you right now are broad jump and Total Body Strength. Together, these account for about 2.9 mph of your velocity gap.

Supporting Work
After that, it's about the supporting package: left ankle dorsiflexion (mobility), Left Lateral Broad Jump, Left Grip Strength (power/stability), Body Height. These aren't the headline levers, but they raise the floor and make your mechanics easier to execute.
Mechanical Focus
Mechanically, the key focus is Dominate Arm External Rotation Maximum External Rotation and Dominate Arm External Rotation Front Foot Strike. Most of the energy to the ball comes through the trunk, so trunk acceleration and sequencing are the big rocks to move.
Dominate Arm External Rotation Maximum External Rotation +1.5 mph

Your Action Plan
Movement Cues:
"Shin down, leverage, drive — use the ground."
Training Priorities:
Build Mass
Calorie surplus + structured strength phases. Mass equals gas — you need more raw material.
Explosive Power
Jump training (box jumps, bounds) + Olympic lift progressions (cleans, hang cleans). Train fast to be fast.
Mobility & Stability
Daily mobility work (hips, ankles, t-spine) + longer holds. Add single-leg stability for pelvic control.
