I disagree, yes. And again, if they have glaring weaknesses, you really can't complain about trying to pigeon hole people because I specifically say, in bold text IIRC, that those people don't fit the 65/25/10 guidelines.
65/25/10 was not "made up." And the 80-84% numbers were made up but make a point - they could have been any series of close numbers. The point there was to show that if you constantly only work on your "slight weakness" it'll be a constantly revolving door… and you're likely to end up at 65/25/10 or thereabouts anyway. It's a hassle and wasted effort to constantly track things down to that nth degree.
You are making stuff up to fit your model. This is called confirmation bias. It seems YOUR mind is made up, so I'll leave you to it..
False. It's easier to get better at putting than to get better at the full swing.
Seriously, c'mon. How long do you think you'd have to train to putt as well as a PGA Tour player? How long do you think you'd have to train to have a full swing that works as well as a PGA Tour player?
It's not even close. The putting motion is simple and easy to learn.
My mind's not made up - I love to change my mind because as a scientifically oriented person that's the fastest way to improve on something - to learn something new. But you've not said anything that makes me re-consider anything, really.
