I'd like to be the second person to say just how absurdly fast that is for an FRC robot. To be clear you're not converting incorrectly, 20 mph is 29 fps. I'm not aware of anyone that's tried gearing for 29 fps, but I doubt anyone has successfully. It'd take most FRC robots (assuming ~120lbs) far too long to accelerate to be practical. As I recall
our team's 'Speed Racer' in 2008 was geared for a free speed of 19fps, which was hard enough to drive... and was on a robot that generally turned rather than stopped... and the robot weighed around 50 pounds with battery (so it could accelerate very quickly).
I suspect something geared for a free speed of more like 14-20 fps would be much more well-suited for a game with demands for a high top speed.
