A simple software adjustment like squaring the drive joystick values makes control in high gear noticeably more manageable, and if we were to change anything, I would say we would try to push it faster before deciding to slow it down.
On our 2013 robot, which did not auto shift, we often had trouble starting in 2nd gear, and it seemed to take a toll on the batteries whenever we tried. The robot simply did not like to get going very quickly in 2nd gear, so we started in 1st and upshifted to 2nd once we had some motion.

Do you have any guesses as to why this may be?
