I wish Polaris would have started the self adjusting deflection 20 some odd years ago. I remember after getting out of the military and coming home to buy my first new Cat and I was standing there watching my cousin and uncle adjust their belt deflection on their Polaris's. My brother and I are watching them and I ask, "What are they doing?" "Why are they doing that." "Do I have to do that to mine?". To which my brothers response was to keep looking at them and just wrap up the conversation with, "We don't have to worry about that, ours is automatic" and he was right, we never had to worry about deflection. That was back in the mid to late 90's. It the one eye roller to me coming back to snowmobiling and switching to Polaris that they are just now going to automatic adjust with the P22. One credit I'll give cat other than the use of the Willwood brakes back in the 90s' was that the primary clutches were solid and their secondary was really good to.
I only made my secondary better by adding a Hi-Tech Performance encapsulated Roller that used a lot of the same parts except helix, spring and rollers needed to be swapped out. (I'm not sure if the company is still solvent or producing since I think Duane passed away about the time of the last updates on their site.)
