When I first came out and shot IPSC, my scores were poor. In the 30% range. That was okay, because I looked for names that were shooting around the same scores that I was, and I'd see if I was "winning" the race amongst people that were consistently the same level of ability as I was.
I shot in the 30-50% range for a couple of years before I started practicing a bit more often and shooting a few more matches. Then, wouldn't you know it, my benchmarks started changing. Shooter A used to be consistently about 10% ahead of me. Could I start closing that gap? I was a C class shooter comparing myself with other C class shooters now.
I was now able to pick different people to "compete" against, and I was also able to identify matches that favoured target shooting vs run and gun. As a run and gun shooter, I would try to beat my target shooter benchmarks at a target shooting match (I hope that makes sense).
I was starting to shoot A class scores, 80-85%. I was challenging some of the guys that I always thought would be out of reach. I wasn't winning matches, but I was doing well, winning the odd stage and finishing top 15 at Level II's.
Then I took a five year break. I came back with no idea how much people had improved. I was shooting 60-70% against people that I had been neck and neck with when I quit. A bit discouraging, but I persevered. I had some new goals set. I started practicing again. I traveled more, and shot more matches - not just in BC, but in Canada and the US.
Am I winning yet? No. I've won the odd level II, but never a level III or Nationals. My benchmarks have changed, though. I know who the shooters of my ability are in Canada (although less so, lately, since nobody will let me look at the Ontario stats.

) and I know who I'm competing against at most of the big matches in the US.
I'll admit that shooting with me may not be the most rewarding experience - I no longer expect people to pick up my brass at matches, and in return I don't pick up other people's brass. There also usually isn't enough time to explain why I'm telling people to do the things they should be doing during a Course of Fire, so I may be a bit bossy in telling people what their "plan" should be.
Still, I try to have fun, and not cop too much of an attitude. I hate RO'ing, preferring to work in the warm environment of the stats shack, although I do miss matching names with faces (I can recognize most of the names/people in IPSC BC). I hate the politics involved with competition shooting, but most of that doesn't rear its ugly head at the range, anyways. I hate the fact that I have to drive an hour (or more in bad traffic) to get to my range.
It's been over 10 years since I fired my first shot at an IPSC match. Since then, there's been lots of reasons to quit. I'm still here. Sure, it has cost me a lot of money in equipment, travel, ammunition and time, but I love this sport. I'm glad I took up IPSC, and I'm not going to quit...ever.
