Agree Jim. Only said it to bring out that other people do fine in this game with other ways.
I said learning with a ding method if struggling is best, and it's as good a way as any to stick with anyway.
IMO the worst way to do it is hardly ever moving the aim marker, and usually doing it all with ding missing. Having said that some have good stats even with that.
Also going that 2 or 3 ' past each time you miss is a good way to weight a putt. A good putter should be able to make those. OK some holes at Merion you don't want to be 3' above / above to the side a pin on champ 13 but short of that a good way.
Some days you will see the line and some not so much I also agree. WGT do vary green speeds, and some adjust better with what is in front of them than others too. Before the actual stimp speeds were shown it was taken as read you went firm first putt in a RG, and just went with what was gauging best you could from that.
Anyone struggling Beth F9 or B9 with their green speed chart (I think basic is fine but many takes), and get some confidence up on say V Fast at most, and then move to more challenging. Will be good and bad days no matter what but stick with it and will come.
Per several vids I have posted I am def not a ding only putter. I work around the ding but oftentimes set up to build a slight miss or more in to hold a line. I did OK in RGs with that (lower level ones LOL knowing my limits)...Big topic and much of it an art that needs to be learned over time, but kicking off with the basics as I outlined for momentum will get especially strugglers a long way too.
