Retrying - pp gains
Not retrying - improvement
Personally, when I get fc on a map it's usually between first 3 retries, if I can't do it I just play once or twice until the end and try to fc it another day.
What I always recommend is
NEVER RETRY. Some people just don't know how helpful it is to play every time until the end and have each play in your playcount have weight behind it. It helps your tapping stamina, aiming stamina, your consistency.
"Oh yeah? There is this one moment in a map where I always miss, isn't it better to just play until I FC that moment?"
Well, no...
There are easier ways to fix your bad habits or just learn to play this unfortunate moment that makes it unable to fc your beloved map. Edit it out.
Go into map editor, edit out the moment that you're having troubles with. Save as new difficulty. Practice it.
It will save you a lot of time and nerves
. Seriously go do it. Good luck!
