Thank you Ether! This is the first post I've seen all season to do a proper (yet quite simple) calculation of how fast a minibot of given weight can get up the pole. I've been meaning to do this with my students all season long, but was too busy with the arm and other things. I think now is the time to revisit it.

Trial and error is one thing. Knowing what you're shooting for, because you did some calculation first, is quite a different (and much better) thing.
