Not sure that proves anything tbh. All the holed putts he hit would’ve gone in the hole if the flag was out. I think the speed of the putt needs to be higher then that to really prove anything, but like I said in another post, anyone who wants to charge a ball that risks going 4ft+ past the hole (if missed) best have a putting stroke on rails to benefit having the pin in.
What this videos shows is that the flag does not have a detrimental effect on any "Good putts". It doesn't look like it will knock out any good line decent pace putts.
It means it would be beneficial to leave the stick in to stop any putts you hit a fraction too hard.
That is a marginal gain and obvious advantage.
