2T vs 4T / Standing vs Sitting / Riding vs Siteseeing
See the relationship! lol
Seat time is your friend and it sounds like you're getting pleanty of it. The real challenge is to push your limits without biting off more than you can chew. Trashing the bike, your body and sometimes even your confidence doesn't help too much. Like others have said the basic skills are the same slow or fast. Probably even harder to do slow (think wheelies). I've never had the chance to do a training day but would jump if I could. For me I have a small trail close to home which is tight (1st gear on the pipe/2nd lugging). Very technical in terms of leaf litter, vines, trees, fallen trees, rocks, vertical drops and rises, and off camber turns. I just go out and see how long I can ride it without putting a foot down. It will take your body language, clutch, brake and throttle control to a new level.
