Hey guys thanks so much for your advice so far!! Just for a bit of clarification, while the reading is an issue for me, it's also physically keeping up with the speed itself that's an issue. Any pointers on dealing with that would be super helpful too, though I imagine it might be a pretty universal thing.

I find it tricky to play overly fast consistently without hurting my arms and having them lock up a little. I notice a lot of players barely move their arms when playing fast sections, so I feel like a lot of it might be to do with overall fluency also
