Good training design uses these principles. Early on, maximize variability — open constraints, diverse contexts, rich feedback. As a solution emerges, narrow the constraints and add repetition and volume to deepen the attractor well. Once it's consolidated, layer in pressure, fatigue, and context switching to stress-test the infrastructure. Always funneling from wide exploration to specific expression, whether within a single session or across a development period. 6/6

Once the solution is known, the physical structures must get upgraded to for execution to become automatic. Myelination increases signal velocity, neural outputs synchronize, and metabolic cost decreases. 5/

Skill development isn't magic. It's a search problem → an optimization problem → an infrastructure problem. The brain explores, converges, then upgrades its physical structures. These processes can be represented quantitatively, giving us a better idea of what's going on during motor learning and what variables can be manipulated. 1/

Live ABs vs Assessment
Experimenting w/ mocapping pro hitters during Live ABs
Interesting possibility to identify how a hitter's swing breaks down when facing an actual pitcher vs when getting their A-swing off in a controlled environment
Could show specific issues to address

segment masses are found through individual segment lengths and a standard model of segment densities (a limitation of the setup). power is the rate at which work is done and work is the transfer of energy - stp (segment torque power) is indirectly influenced by segment mass since that impacts the segment moi and therefore the toruqe/moment
English
I believe that segment mass is largely determined by anthropometrics and then distributing the weight based on calculated cylinders. Not super sure how V3D does it with marker less @bl0ebaum correct me if I’m wrong.
Regarding work done on the segment, I believe it is calculated from the joint moment and angular velocity. Segment mass is largely irrelevant.

A 100mph fastball is 144 Joules of kinetic energy.
A pitcher at peak leg lift has 1,204 Joules of gravitational potential energy.
The mound stores more energy than the ball needs. The body just can’t transfer it all cleanly.
Throwing is thermodynamics. 🧵

Congratulations @hedgertronic on signing with the Texas @Rangers ‼️
Check out Josh's outing during Pro Day in Tampa, FL.

two weeks after releasing RF-DETR segmentation, @DrivelineBB started testing it in their baseball pitch analysis pipeline
it only took ~30 minutes to train this model

RF-DETR-Seg outperforms other real-time instance segmentation models, including the YOLO 26 segmentation models released last week link to my stream covering YOLO26: youtube.com/watch?v=sczVkn…

Hoping for good results from DL pro day in AZ and TPA today!!! You will not want to miss the 1:15 slot in TPA! x.com/hedgertronic/s…

Tyler Rogers is the only MLB pitcher with an average release height under two feet. The focus of my off-season training has been lowering my own release point from roughly three feet to Rogers-range, but twelve years using the same slot has grooved an extremely deep attractor well. Early in the off-season, @Crider_HP programmed variable slot and implement work to destabilize my old angle and open up different solutions within my movement landscape. More recently, I’ve built familiarity with my desired slot by constraining start positions at/below the goal, adding rhythm to access the new angle dynamically, and then using variability/representative context to stabilize the pattern. My recent bullpen average? 1.8 feet. Good training, as they say.

For a thrower who has saggital flexion/extension positional and timing problems in the throw, the first step is to make sure they have access to those ranges.

Representative task design.
I have some thoughts about how to create more representative practice environments as season approaches.
Not surprised this behavior exists at all.

@RobertStock6 there was a saberseminar presentation the year before last by auburn that looked at performance vs biomech data from the lab vs in game and it was shocking how much of the relationships observed in the lab broke down looking at the in game data
