if you just fc you will almost 100% get 99%+ acc anyways. i have plays with like 20 misses and 200/2000 combo max but still 97% acc+. only getting an ss might be hard but sometimes you just randomly get that as well.
on the other hand fcing in catch is pretty hard if you ask me because the nerves and mindblock can impact you a lot. it ofently happens to me that i fc until the end and then die. and i don't blame the game... it's just me getting nervous, i think if i make it through even though i was nervous, then i deserve those extra pp.
