Let me just make sure I understand your question.. You're wondering if the higher the punch control percentage, the softer your E-Revo will accelerate off the line when you go from a stand still to WOT (wide open throttle, or full throttle)??

If that's the case then the answer is the opposite. The lower the percentage the softer your E-Revo will accelerate off the line when you "put the pedal to the floor" so to speak.. Putting the punch control setting to 100% will put as much power to the wheels as practically possible when you hit the throttle. Running 6s LiPo on a MMM with punch control at 100% I do standing backflips with my E-Revo, meaning rather than doing a wheelie it'll just do a complete backflip and land on the wheels.

A side note and a word of caution on that, I wouldn't recommend doing these 'torquing acrobatics' unless you have a full metal drive system, meaning metal everything from the motor pinion to the tips of the wheels. It can handle a lot, but I drive quite aggressively with it so I like to play things decently safe in terms of the frequency of replacing parts.
