Just curious. I recently had to send in my GPS puck to Perfect Pass because version 9 was not seeing the GPS. So we are using classic mode. Been a while since I have used it. Question: Once it is locked in on the baseline RPM, does PP increase/decrease the RPM while pulling a skier or does it just stay at the RPM set for that speed? Just wondering? I will say this, Classic mode sure does make running the course a bit easier.
