Another thing to do would be to alter the experiment. Replace your current axle with a conically shaped axle, that will release the weights at ~zero velocity immediately before they touch the ground. This eliminates the dropping mass kinetic energy variable.

I'm sure there's a mathematical model for this, but my math skills are pretty much gone.
