Don't misunderstand, we shoot for fun. I think the AZ Blockers were a lot of fun. My perception is that the matches were more competitive than they would have been otherwise. The scoring opened the door for some shooters to compete with some super fast competitors. They were still talking the next day about how that .330 got beat by a hit in the black. "Well, you should have been in the black too!"
Bias! The Arizona Five has a gunfighter bias. The 10 foot target has a speed bias. Some would say the scoring has a accuracy bias (a myth). It all balances out. "It just practice, man, practice, what are we talking about, practice, man, practice."
But even if you are having fun you might as well be getting better.
Perception vs Reality: I did a spreadsheet to verify my perception that shooters improved, however it only dealt with hit percentage and "in the black" percentage. To further verify what I perceived, I have calculated the gunfighter rating for all of the matches. Generally, the rating of all of the shooters improved significantly from round 1 to round 7 except for Shady. He started at 1.590 and maintained that near perfect rating in every round.
Improvements: If we ever do this again one change I will make is to record the fastest actual time as the fastest time on the score sheet. That will be easy to do and then the fastest time report and bracket report would be available for data analysis. I think I can modify my spreadsheet to input the fastest time for each match and the computer would automatically compute the rating for each match if I get the formulas correct. Might be useful.
Heh, those obsolete 24 inch targets may be of use to you and you might get better too. Remember:
Never ever slow down;
Never ever worry about where you are going to hit; you are going hit where you are aligned.
Never ever worry about speed; what you got is what you got, worry only slows you down.
Never ever practice missing;
