There have been great players throughout history doing things that aren't correct and just because they were great doesn't mean its right.

Yes it does! Just because a swing doesn't look like Ben Hogans doesn't mean it's wrong (I know you didn't say Ben Hogan) but that is what is implied.

That's the whole point and beauty of Homer Kelley's golfing machine, there are a zillion (I know it's not a zillion) different ways to 'Do It'. And, the most ideal way might not be possible for some (for whatever reason be it physical or mental) so they find another.
