Classifiers Quality, Difficulty & Partials
Classifier Quality varies depending on how well scores correlate to a shooter’s major match performance and overall classification percentage.
Classifier Difficulty varies depending on the shape of the distribution; it can be defined as the average score as a percentage of the Recommended High Hit Factor (Rec. HHF).
Easier classifiers are generally "better" than harder ones.
Partials, Virginia Count, Weak Hand Only (WHO), Strong Hand Only (SHO), and Mandatory Reloads make classifiers harder.
Most stages in Major Matches do not feature Virginia Count, WHO, SHO, or Mandatory Reloads. This causes classifiers containing these elements to correlate poorly with match performance, resulting in lower quality compared to more "stage-like" classifiers.
Vision, Splits and Transitions
There are two often repeated ideas within practical shooting training discussions that I keep noticing and don't entirely agree with:
Vision Focus
Transitions are more important than Splits
These things aren’t entirely incorrect, but in my opinion, the way we implement them often lacks depth and shouldn’t be the same for all levels of shooters.
USPSA vs IDPA for Defensive Shooter
If you have access to both and are new to competition -- I suggest you pick USPSA over IDPA. But if you shot USPSA for a while, you might find some new challenges in shooting IDPA as well.
