AnaNikolaj:
I can see the 1st attempt going that long, if the downslope continues after the hole, which I think it does on that hole. For example, long pin on Merion #3, if that putt goes a touch long on 13 speed, it just keeps Rolling, no matter what the elevation states. But the 2nd putt is though to explain, unless there's a sideslope uphill, kind of like CB #12, putting from the lower edge of the green with your putting line going through the side slope.
Appreciate the input, but not even close to what you are describing AnaNikolaj. First of all there is not that drastic of an elevation change anywhere on #18 green @ PGA National. In this case I was just over the green in the fringe between the right side pin and back bunker, most of the break was R->L more than uphill/downhill. Secondly, in what you describe I would expect the ball to narrowly miss, then just keep trickling and trickling, perhaps even slightly picking up speed after it hits the more severe downslope past the hole (been there, done that). This was not the case at all here, all of these putts are coming off the face of the putter like a rocket and racing by the hole.
Heck, one of the short ones I posted about earlier (talking about 4-5 feet) from the other day @ CB I used 15 meter @ <25%. The thing hit the back of the cup so hard it popped up in the air and still went 20 feet past. (I'm surprised they didn't stop play to let the grounds crew come out and repair the damage to the hole!)
Last night was a back 9 CC tournament @ PGA Nat, Champ tees/greens, moderate winds. I was -4 through 8 holes and looking at a makeable eagle putt on the last, gimme birdie at worst. I only mention this to show I do 'sort of" know how the game works and how to play. And while I'm not immune to a lapses in judgement, or not paying close enough attention, or bumping the scroll wheel, this is not the case 4 consecutive putts in a row on 3 different holes over the course of 2 days.
Maybe next step is to research how to record games so I'd have some video to back me up next time this happens.
