I think that you can probably gear for like 26fps and put a software limit that can be increased with driver practice. As long as you have a low gear you would be able to stop yourself from getting stalled easily.

ONLY if you have a low gear/two speed gearbox. Your acceleration will be impacted significantly with a top speed of 26FPS, which may mitigate the perceived higher top speed (not useful if you never get there). Personally, I would only design up to 24 theoretical, because beyond that number most drivers seem to struggle controlling the robot.
Top speed isn't the only thing to consider when choosing gear reduction. We factor in Driver Ability, Game Requirements (open field, field with obstacles) , and Robot factors (such as weight) when choosing the reduction.
This year we were geared for 18 FPS, and achieved 16 actual due to a robot that only weighed 107 pounds w/ battery and bumpers. We thought it was a good harmony between speed, and torque (we run single reduction). If we were to run a 2-speed, the actual would likely be bumped up to 18-20 FPS actual because we can now have a low gear (5-9 FPS) for pushing
