Thank you so much, this is very insightful! 
I was suggested to switch to J5 to make things much easier and I gotta say it has considering I always stay ~87%-94% primarily on 7.x songs. I also learned to add offset since I noticed the notes would come slightly earlier than the song, so I am using -0.026000 global offset and it feels very nice to acc. I am assuming my keyboard responds well to stuff, however this will be pretty hard to notice due any inconsistencies to my lower skill level.
I will definitely have to figure out what my strengths and weaknesses are so far considering the fact I am kinda just playing songs that seem interesting in a specific level range from 6.3-7.8 (sometimes trying 8.x stuff). I am going to have to change the retry button so that I forget retrying exists since it can be a burden on mindset. I am more than willing to play some easy content for sure 
I’m finding my technique as well considering wrist down elbow up feels natural to me although I’m assuming that’s just preference and could learn how to hybrid (wrist up for jacks) for faster stuff in the future.
I will definitely have to keep alot of these tips in mind when playing.
I notice the statistics say I play “technical” maps alot, and am lacking in handstreams according to my profile, got any handstream packs I could play?
I’ll probably contact you on discord in the future if I have any extra questions that may not retain too much to this thread.
