These threads are starting to get really old really quickly.
For the op's benefit take a look at this, after 2 19's, I decided to record my 3rd attempt and made 19 again in the par 3 ready go, this should have been an 18 but I parred the easiest hole of the lot at Cabo and of the 19 shots, I dinged 8, 5 of which were with the putter.
19
If that doesnt convince you then take a look at any of the 42 vids I have on my channel, scores from 26's/27's and 28's with all sorts of different balls. Recording is not an ego trip for me so you will also see 30's where I make mistakes, the beauty of recording myself is that I can watch them back and learn something from them.
To this day I practice and try to learn something new each day, do you? Might be that the one you should really pay attention to is the putting tutorial :-)

There are many many players who record their videos because it is fun and adds a little extra pressure and they are a great learning tool. Some like myself made the very first video to disprove allegations just like yours and then I got addicted to it lol
If you still believe your inital theory after watching some of mine or any of the other 100's of great videos you will find from top players, then carry on with your belief, the only one who will be held back by that belief is you.
"Just coz I cant do it, the rest must be cheating"
Makes as much sense as a chocolate teapot!
