I honestly think it's a defence mechanism or wishful thinking and I understand why. If you have swung a certain way or followed a certain coach and then data drops that questions it you would prefer it to be wrong or convince yourself that the other way is just as valid.
For me the handle dragging, hold angles.elbow leading stuff has destroyed my game for decades. Its still being taught by plenty out there. It's so ingrained in me that I'm not sure I can get it out of my DNA tbh.
Most of us when we start just throw the clubhead at the ball, its natural to do do, we are not very good but that's expected we've never played before.
Then after a while and getting a bit better you start looking at why you hit it fat thin left or right. If only someone said you need to stop swinging with your body and club at the ball. Do this instead it will feel totally alien to you and get help and stick with it.
I blame golf digest and that local pro who also read golf digest for going in a totally different direction :-)
Anyhow I'm off for a round and I'm sticking with what I've learnt from the data this time until that bad hole where i feel that snatchy moment again, one partner will say j was too quick, the other I need to keep my head down. I know deep down I was just trying to save it, my need to pull on it like a madman again. Anyhow it's only one bad sh........
Wait that Johnny Miller said pull the handle into the wall, I'm a puller and can't stop, maybe dragging can work. Miller was better than AMG at this game and have you ever seen Eamonn D'Arcy, looks like he's been tazered when he swings, he was good.
This is the magic move, handle into wall, cant fail, well it did last year when i tried it and the year before. In fact ive tried it hundreds of times. Gonna stick with it this time mustn't have been pulling hard enough.
