Empirical testing is not science, is that your view?
What is exactly your complaint about the scientificness of Dan Plan?
Clearly dan the plan, is an empirical experiment testing the waters of that 10 000 hours theory.
For the record, I have a hunch that Dan will not exactly be the shining start on the PGA tour. I think he needs way more clubhead speed than he currently has to be competitive at that kind of level.
I do think that he could get to scratch level though...
I do agree with you on that he should post more detailed analysis of his own golf game, so everyone could see what he's up to. See the data so to speak.
If he had done empirical research of golf and specifically golf instruction before embarking on the 10,000 theory then I would agreed he started in the correct fashion. Instead he spent an ungodly amount of hours making 1 foot putts telling everyone he was going to make the PGA Tour when he had no idea what separated him from a PGA Tour player. Basically after 3 minutes of hitting 1 foot putts he had accumulated the same skill as a PGA Tour player hitting a 1 foot putt. Yet he was no closer to being a PGA Tour player after those 3 minutes or 30 hours he spent hitting 1 foot putts.
