This is true, your approach actually optimizes the gear ratio while mine does that manually. I do like that it can solve for gear ratio instead of just sprint time to distance.

This is probably worth of an entire separate paper or more, but I don't think it has been discussed much on CD.

33 optimized with sprint distance in mind in 2013 and 2014 as well, based on analysis I did post-season of our 2012 robot where we did not optimize to sprint. I eventually concluded that a short-spread shifter was a good thing in FRC (1.8:1 or so between gears), rather than the wide-spread shifters currently used (e.g. 2.54:1 and 4:1 AM shifters) because of sprint distance reasons at moderate distances vs full field distances.
