I'm averaging 16, and I'm not sure how impactful it has been because I took a long break from cfop after learning most of oll and just finished it up recently. I would say I know all of the algs well except for 1 or 2 that I have trouble recalling.

So, I've just finished learning full OLL and I was wondering what would be a better use of my time: planning first pair in inspection, or 2 sided PLL recognition.

You have to make sure it is in the right direction. Depending on the alg you use, you want to have the swapped edges in either the front left or front right.
