Haven't they been doing that for at least 50 years? This research article, while interesting, doesn't prove anything to me. It doesn't offer me a new perspective either, I've always held it as a truth that (almost) any player can reach master strength with the right ammount of effort. This article seems to add no more than the estimation of 11,000 hours, on average.

I can't relate to the number of hours either. 11,000 hours is like 460 days.. In how many years? The entire chess carreer, but how long is that on average?
