What is Your Most Perishable Skill?

[cheby]

For the last two years I had to take several months breaks from training each year due to injuries (Severe case of elbow tendinitis to the point that I could not move my trigger finger at all and the broken wrist last year). Here is what I noticed when I started shooting again. I was doing everything as good as before the injuries but slow. Especially target transitions, and hoser stuff such as a bill drill, and 4A's. What is interesting, the long distance drills suffered the least. It took several months, at least 3-4, to get to the same level as before in terms of speed. Daily dry fire pushing speed.
Perhaps everybody is different but I believe the speed is WAY more difficult to improve than accuracy in general. And it is the most perishable.

Grip, shooting at distance and shooting with only one hand.
