2nd day switching to KBM in Fortnite. I'm improving a lot faster than I expected

It's just kinda coming natural to me with how much I practiced aim on controller. It sounds weird because it's a completely different input but apparently some skill does transfer over.

My aim is shaky for sure but I'm killing people in Blitz and actually hitting shots. I'm doing Aimlabs training also, very first day it says my score on certain tracking tests was in the 90th percentile.
