This is what a putt looks like, by hitting it too hard. putt hit too hard I hit this putt for 6ft. Those 2 replays were not hit too hard IMO...
Not relevant I'm afraid. Both the putts in question were on severely downsloping greens, so the back lip is lower than the ball. The putt you have demonstrated is uphill, so the putt is crashing into the back lip which is higher so is acting as more of a cushion.
I tried to get 2in above the hole on the first 5 at Merion and failed because the putts kept dropping. This vid is from hole 6, which is the least sloping pin location of the holes I played. 3.5ft of power down to 3.3ft ghosted over, 3.2ft dropped. On a more downhill pin location, like the two putts in question, this value would be lower. It should also be noted that there are varying degrees of 2in from the hole. Overhanging the lip still rounds up to 2in. You can see that both the putts in question were severely overhanging, closer than the test putts I hit in the vid. This phenomenon has been observed with as little as 2.5ft of power, and will be when the ball is both overhanging and on a severe downslope.
The player that thinks he only hit it 0.6in is using a putter with a lowest scale of 25ft. This would be 2.4% of power, which is very hard to achieve! Perhaps he means the putt only travelled a few inches. This is because it smacks into the back lip and dribbles over, making it look like the putt has dribbled dead weight over the hole.
