WGTicon: You are assuming that course/grid is perfect when it's not. There are many many spots on green where it's not. That's why when that putt missed, you make a note. Either mental or on paper or in excel that on this hole, from side this, while it shows no break, ball does break full cup in that direction. Next time you are there, you will make the putt.
What is the point of having the grid then. When I'm putting, I don't ever consider that the grid may be wrong. For the ball to break a full cup, that would be a pretty substantial break not to show on the grid. Looks like its a lottery, just like the wind on SA 17th hole.
Tonight, I entered Saint Andrew's Front 9 Ready Go and decided after my recent bad placings in other tournaments, I better go and do a practice round first. I set up the practice with the same conditions as the Ready Go and started the game. By the 5th hole I was 5 under. By the time I teed off on the par 4 9th, I was 6 under par, with 9 being a very good birdie hole, or even a good eagle chance. I tee off and end up just short of the green. I set up my chip and swing, only for the game to freeze. So I think "O.K. I just shot a potential 29 in practice, so its time for the Ready Go".
World of difference. I struggled and I mean struggled to shoot 32. There were at least 2 putts that should have been in the cup. One of which is saved and viewable on my saved videos.

The ball is hanging in the hole and never dropped, defying the laws of gravity. And that putt was hit more than hard enough to drop as I always ensure I add extra to the putt.
So, to sum up, I agree with the OP.
Anyway, Rant Over.
