although most of part are fit for ar8.8
but i still thinik using ar9 for those jump part will play better than ar8.8
Idk, when I nearly sightread fc'd it 2 months ago the jump parts actually felt easier to aim because I had so much time to determine exactly how I needed to move my arm/wrist joints to move my pen from point a to point b. https://osu.ppy.sh/ss/6026708 (The miss wasn't even on a jump. I just forgot to press a key down 4head).
I'd be interested in seeing more people experiment with lower ar (ie. 8.X) though. I feel like most mappers grew up as players on higher AR so they simply suck too much at reading to appreciate lower AR. A lot of your unranked maps are 9.0 where most would use 9.X which is honestly a breath of fresh air.
