What exactly is the problem you're experiencing with jumps? If you can't seem to reach the circles, your could see if raising your sensitivity helps. If controlling your cursor seems hard, your sensitivity may be too high instead. You also mentioned that it takes you days to hit a decent score. That sounds like you retry maps a lot, which really isn't good for consistency. Judging by your top plays, you should also play more long maps. Going back to a lower level of difficulty (in your case, maybe low-mid insanes) and just completing a lot of maps once may also help.
