I did the same analysis four years ago and quickly realized it was not a good gauge of progress. The implication is all non alphas are equally irrelevant, but they're not. Mike's and no shoots are killers, you need to stop shooting them if you want to score well.
Like Jake says, "slow down and get more As" indicates a counterproductive mentality, you don't get more As by slowing down, you get more As by aiming at the A zone and shooting it. Don't focus on shooting fast, focus on doing everything else fast: movement, reloads and draws, that's where most of your time is wasted. Developing a good stage plan and executing it well is the best was to score well.
