10/15 or less, I prefer it pulled. Anything over that, i leave it in. Something about it being in on those closer putts, gets in my head.

I line sight putt. I visualize the break, then start at the hole and trace the suspected ball path with my eyes back to my ball then putt the ball after a slight pause.

So, with the flag in it makes that process harder to evaluate. So, I always pull the flag. Sad part is if I don't pull the flag, my playing partners leave it in and if the finish the hole they walk off. So, then I either make it known I want it out or just putt anyway.

I don't make many putts with the flag in, and I've hit the flag and end up missing the putt.
