The widely accepted 10 general physical skills are: Cariovascular endurance, strength, stamina, flexibility, power, speed, coordination, accuracy, agility, and balance. The first 4 are organic (measurable). The last 4 are neurological. Power and speed are equal parts both.
In terms of what we do in practical shooting, I believe that the vast majority of our skill level and improvement comes from neurological gains.
I'll probably get a lot of flak for this one, but I'll put myself on record here and now saying that I don't think it is possible to improve your shooting ability if you are calling 100% of your shots accurately. In matches, that's exactly what you should be doing. In practice, you need to be pushing the envelope if you want to grow and adapt.
