Torque vs. Speed
Okay I'm sure this has been discussed somewhere. I have searched but couldn't find exactly what I wanted...

I recently had a discussion with our team's programming mentor. I told her I had designed our prototype drive train to run at the desired speed when the motors were turning at 50% of their max speed. I did this because I figured at this point speed and torque would be highest (proportional to each other).

She said that in reality 75% of max speed is a better number to aim for, and that 50% was just theoretical. I then asked my dad and he said it didn't matter, and that 100% would be just fine.

So who's right? I don't want my drivetrain running at max power constantly just to maintain the desired speed. That would drain the battery. I also don't want to have poor acceleration because there isn't enough power.

Any help?
