yeah......it depends on your ability to learn as well. if you learn quickly, the # of hours will decrease.
when I was learning to switch hit in baseball most books that I read said you need to take about 30,000 - 50,000 swings on the other side of the plate to be equally capable. (or practice about 3 years). well, I've been doing it for a little under a year and am already more capable on the switch side (left). while I don't consider myself to be a particularly quick learner, some people do. it all depends on what your pace\learning abilities are imho.
if you're already a very good photoreader you are probably ready to start teaching other people how to PR. I don't think you'll need to invest your 1000 hours.
