My point was/is this...

21 days, 32 hours, etc etc all that is inconclusive.

Getting better through practice is different for everyone, so it seems.

If 21 days at so many reps worked, and that's all it took...wouldnt the top flight players improve off the charts? It took Ernie (I believe) almost 2 years to stop laying the club off, no?

Ah, nevermind!
