I just punch the shutter button and pray. :) Ted Grant is the guy who's been known to spend the day before the event trying out his gear on the race cars so he can judge when to push the button to get the shot. The common sense logic is: when you punch the button and the autofocus decides to spiff thing up a bit, adjusts the lens in, and then out, until it's just right and then trips the shutter two seconds later, your decisive moment may have passed. That's bad. Is the difference between 10 ms and 100ms meaningful? Well, a car traveling 100 mph goes about 15 feet in 100 ms and only 1.5 feet in 10 ms. A bicycle traveling 33 mph goes 5 feet in 100 ms and 6 inches in 10 ms. Most of my exposures are of much slower stuff. Still, the difference between 10 ms and 100 ms is the same as the difference between a shutter speed of 1/100 sec (10 ms) and 1/10 sec (100 ms). If those differences are meaningful to you, then the delay may be too. If you are experienced enough to judge the delay it doesn't matter (much). If you aren't, or haven't adjusted to your equipment's limitations, or prefer 1/100 sec to 1/10 sec, it can. You can learn those limitations by taking a thousand shots and studying the results, or you can learn them by testing and measuring. It's OK as long as you do it somehow.
