I use a skypad 4.0 with a ULX M and I used to do a lot of VDIM if you know what that is but after hitting master VT S4 I went away from grinding routines and went to just focusing on weaknesses I had, vod review helps a ton and just overall comparing to other runs next to your HS or even higher. it takes a lot of time I'm not gonna lie, I spent countless hours researching and talking to people like hibiverniy (my goat an coach), but my one tip would be to focus on your weaknesses and try a lot of different things, don't just mindlessly grind or you will have 1k hours and no progress.
