I shot a couple of IDPA events last year but really started training seriously late in the summer, then scheduling conflicts et cetera didn't permit me to shoot again until last month and I shot my 5th event yesterday. So I am far from an advanced shooter, but I keep a religious range log, I analyze every drill, Shoot more on the clock than off, and record myself as often as possible so that I can see my mistakes. I am also a data geek so that helps.
I have been attempting to track my progress against other local shooters and I have come up with metric that I think makes sense, but I wanted to see if it passes the sniff test here. The metric is "% of the High Division Corrected Score"
I have attempted to control for the differences in division by normalizing the times based closely on the different classifier times. So for each Division I adjust the match score by multiplying by a the following factors.
ESP: 1.00000
CDP: 0.97435
SSP: 0.94750
ESR: 0.89000
SSR: 0.87350
I then divide my time by the fastest corrected time of the day to calculate my metric. (On one occasion there were no masters at the event and I created a fake time to approximate their fast time to keep it reasonable)
Obviously there is considerable bleeding of classifications at each match but I have found:
The average Master time is within 10% of the fast time. (<110%)
The average Expert time is about 25% slower than the fast time (~125%)
The average Sharpshooter time is about 60% slower than the fast time (~160%)
The average Marksman time is about double the the fast time (~200%)
And oddly the average novice is slower than the average unclassified shooter.
Does this analysis fit with what you would expect? I believe this is an approximation of the USPSA rating system, only at the local level. As an unclassified shooter I have been looking for a way to find a "peer group" to compare myself against and to benchmark my progress against changing fields of shooters.
Based on these results my progress has been as follows...
March 27, 2010: 1.877299987
May 22, 2010: 1.912255795
