How far in advance did USPSA advise members the Aug classification would be the one used for the match? I know it was several months. Was it prior to applications being taken? If so, no one who attended the match has any reason to complain. If a competitor failed to notice that detail, it isn't USPSA's fault.
It was not within the USPSA admin staff's power to ignore the rulebook. Prior notice is not sufficient, you can't line-item out pages of the rulebook because it's inconvenient. Ask the second place finishers of each division/classification if they mind going home with a $100 gift certificate instead of the pistol they would've won when the first place finisher had been correctly classified.
I already have a job. It's hard and I'm good at it. My boss doesn't accept excuses.
uspsa explained they would use the august update on every entry form before anybody sent any money in why are you so upset about this
