have you heard of Exerwin?

the developer took data from crossfit and many various competitions around the world, and after some statistical adjustments constructed graphs that correlate well across the age & gender - adjusted performance across a whole variety of exercises from bar hang, grip, and plank to snatches.

i recommend to read the description at https://exerwin.com/philosophy.pdf

i have been pushing the developer to work on integrating lightning like you did, but he lacks greater vision.
