Less attention on how a "drill" can be configured to fool people in a training environment ...
... and perhaps more thought to how we might be less susceptible to being caught by surprise to the extent that we may never recover enough to catch up in identifying the
nature of our attacker, and the actual
manner & extent of the "threat", and where our "attacker" is in his own OODA Loop.
It's not just "draw speed" that matters (and it's actually a much less important criteria outside the classroom, and off the gaming range, than some folks might like to think).
Our first "reaction" is being sufficiently aware to be able to
Observe & Orient, and then our training (including both knowledge and skillset) can help with the
Decide part of things ... and then the circumstances involved, and our sustained skillset development, might help with the
Act.
It's not just a matter of 'slapping leather' (or plastic), even though many folks who own shot timers might like to lean that way.
The speed at which someone can "cock" and prepare to initiate a punch, and the speed of the punch, itself, doesn't necessarily mean it's going to be effective.
Gear possession is good. Familiarity and the ability to use the gear is better. Relying solely on the gear an using it, under optimal training and practice conditions, is perhaps less of a "predictor" of potential successful application than we might wish ... even if it makes us feel good about ourselves and having the gear.
Big picture, folks.
