That actually sounds right. For me, they took 80 or so to race what I subjectively thought of as "well", but they only took 10 or 20 - as you said - to roughly figure out what they were doing.

And I figured out what the behavior difference was: before they finally "figure it out", they spend most of their time spinning in place or moving in "epicycles", for lack of a better term.

Thanks for the project; it's been great fun!
