One of the areas I desperately need to improve this year is my first shot if I've any hope of making USPSA GM. From my L10 set up, I can get 100% hits on a the A-zone average time around 1.25 seconds from the draw at 7 yards. Pushing my speed I can shave that down to in between 1.00-1.15, which is pretty nice all things considered; but to get that extra 0.2 my "risk" factor goes up considerably as I'm only getting about 80% hits in practice.
It's even worse in IDPA, where my first shot to a down zero from concealment is around 1.40, and to get down to the 1.20s I'm looking at 75% accuracy. In USPSA, the risk/reward is a wash if I'm shooting a charlie in 1 second vs an alfa in 1.25 seconds (both have a HF of 4), but in IDPA the risk/reward makes a 1.4 draw to first shot to a down zero a much better idea than a 1.2 (-1).
That's just the first shot, because when I push my speed to get the 1.2 from concealment or the 1.05 from open, there are times where my grip is messed up, making my transition/follow up shots more difficult, that's where the risk/reward starts to skew towards having a slightly slower first shot in exchange for a better grip and a higher percentage of a good hit.
And don't even get me started on drawing to low percentage targets, because that's a whole different kettle of fish. I'm about 2500 rounds into this season's practice, and finding that risk/reward balance is going to be a major hurdle towards making GM.
