Yeah, and I'm saying that, given the instruction, it's likely not a matter of "figuring it out." It's more likely that he just doesn't quite have the physical capability to improve that. One cannot "figure out" how to improve eye-hand coordination, or how to accelerate fast-twitch muscle response. These things pretty much are what they are, and they vary from individual to individual.
I agree with your assessment of his likely success. I just take issue with language that implies "he could if he really worked hard enough," when that may simply not be possible.
