I don't think that's accurate. I'd say if we actually hooked up everyone's robots to a dyno and tested their actual drivetrain efficiency, there would not be many with greater than 90% efficiency. I'm not saying worm gearboxes aren't less efficient than spur gearboxes, but 90% efficiency is nothing to complain about. I've always been impressed with Category 5's drivetrains in the past, so if they say it works well for them, I'm liable to believe them. Though I do agree with what someone said earlier (and maybe in another thread) about attaching the modules from the bottom, not the top of the frame rails.
