In point of fact...I'm starting to believe even 90% of the points isn't enough...
On subject though.
In my case when I am shooting I am not consciously thinking "Ok if I want to get at least 90% of the points I need to go slow here, speed up here, etc."
I figure out my percentage of points at the end of the match so it has nothing to do with how I'm shooting during the match.
I don't necessarily believe this translates towards accuracy but more towards visual patience and consistency. If you understand the fundamentals of shooting, you can shoot an A on any target at any time...once you can do that it is no longer a question of accuracy, but a question of seeing what you need to see to do it.
I believe that the 95% of the points goal is not accuracy based....In our sport there is nothing based on only accuracy or only speed...it is both or nothing.
I guess what I'm trying to say is for me, I akin the percentages of points I shoot to my focus...not my speed. In that respect I don't believe we need to slow down or speed up to hit the goal, just shoot when the damn sights say it is ok to shoot.
Now I have sufficiently confused myself to where I will spend days thinking about this.
