I like to know how things work. That being said, I need to stop tweaking PP, but just a few question that I am sure folks on this forum can easily answer. I have been using Classic Mode for a while and like it, seems a bit easier. Classic Mode is RPM based so why would crew weight and skier weight make a difference? Doesn't PP just try to maintain that RPM? Also, to get times in Classic you still have to autocal the system then map the course, correct? Using Classic I am getting an entrance gate beep and a beep at each ball so it is using GPS for that, right? Sorry for all of the questions but I am certain you guys have all the answers. Thanks so much. Tom
