I agree completely. I also don't know how much of the difference when these ratios are engaged that will turn into pure acceleration either, as opposed to slip. I don't think I can know before I test it, unless you do. I'm with you on the idea that I should overcompensate for slippage with extra power, seems i might have that. What if I spend more time accelerating to match the pulley rpm instead of slipping? I'm sure some time will be spent moving forward, it can't all turn into kevlar and rubber smoke.
