Dave........Actually, my 2.9 Ft. calculation per 10 Ft. of distance for "Championship Speed Greens" DOES work. But, I know, I still need a LOT of work putting on this green speed.
Just now, I played all (18) Holes @ WGT's Best Of Par 5 Holes.....Black Tees....you know, the normal WGT course (not in a Country Club). I kept track....I hit 12 of 18 (1 putts) during that round.
Everyone in this thread has had some VERY GOOD comments.....which I appreciate.
IMO....too many players get all caught up in the "calculations" when putting. Because, as we all have learned.....every single green has some ODD slopes. And, putting from every direction of every pin location varies. I realized long ago, that I just HAVE to get very familiar with every green. Because....even if I do a perfect calculation, if I don't KNOW the green, my putts could be short or long.
I rarely move the "putting target" when I put. I hit left or right of the ding, when I have a break. I putt here on WGT like I putt on a REAL Golf Course.......by feel. But, know that I have to calculate to be able to get most putts close.....then, it's by feel and knowing the greens.
I have NOT upgraded my clubs or putter....nearly as I high as I should have by now....and I think it's hurting my game. I used to buy expensive balls.....but, now play with cheap balls....that makes a difference too.
You have a much better putting average than I do....so, whatever you're doing, it's working for you.
