There are many ways to cut it down. The stroke does appear at least to be a little jabby but I am not finding anything wrong with that.
Put a tee peg in the ground a bit behind to stop u making too long a stroke.
Suppose I started with short 3 foot putts and tried to keep the stroke the same but applying a little more power into 9 foot putts.
I've read that this kind of stroke was used on slower greens in times gone by.
I thought it was a pop stroke similar to sneds but he does it differently. He has a long backswing then accelerates and pretty much has no follow through. That sounds pretty much like a jab to me and he putts pretty well.
My thought is small back and accelerate into a slightly longer thru swing.
