Actually Enchance Pointer Precision is less of acceleration and more of prediction, just like that additional option in osu!'s mouse sensitivity.
Unless coupled with a driver of its own, usually regular mice have mouse acceleration whether you like it or not. I played with mouse acceleration for a few months before switching it off, and that was when I was getting rather good with insanes. It took a while to get used to, but in the end I was able to do larger, more controlled jumps than before.
On topic: I was barely passing them in my first month, starting going apeshit on the second, and finally cleared them no problem in the third. Of course the standard during those times were drastically different from the standards today.
