JFidanza:
When I choose a significant off-ding it's usually because of a major slope and I want my ball to stop near the hole.
Sometimes I won't move the aim off the hole, it's all about the situation...about how big the slope is, or how hard you will hit, and how hard you will off-ding.
Even if the putt misses, the 'spin' will stall the ball nearby. The aim will depend on the slope, power applied and how much you intend to miss the center 'ding'. Generally, you may need to add some power because of the off-ding."
Note: the putt in the middle of the vid was around the ding and it rolled down the slope, several feet away, the miss-ding stays by the hole.
I'm a ding putter and an off ding putter, as needed.
This was a massive off-ding against the heavy slope of STA #2. Notice how the ball is slowing down as it reaches the hole. I don't think I even moved the aim more than 2 feet off the pin. I think I clicked about 65% before the ding line. ('pulled' putt)
Replay STA 2 off ding
If I wanted to ding this shot, I'd have to aim approx 5+ feet left of pin, then dinged (attempt to ding, as the meter speeds up around the center*) at the right power, but the ball rolls up and against the slope, then the slope pushes it back down it it gets momentum and if it doesn't drop it may keep rolling., esp. on a slick green like tournament or champ speed.
* that's another point about intention miss-dings: the center ding line is commonly the point at where the meter is moving at its fastest. So, a solid ding is most challenging.
edit:
This was a massive approx 90% past ding putt, some extra power added. I even aimed a little left of the hole WITH the slope, just to pull the ball back down, which is a little atypical. If I would have aimed far right for the slope, as typical, then dinged the shot but missed the hole, I bet it would have rolled down the green because of the speed coming down from the cant.
If I were using a 'pull' or pre-ding putt in a reversed situation, I would have to add maybe even more because, for me, it seems a pre-ding putt spins and stalls faster than the post-ding putt as mentioned above. Also, the arc of a post-ding seems wider than the pre-ding putt.
