Interesting to watch your putting methods. It appears that you are using ALL of WGT's devices (putter pal & the putting target) to help you.
I feel sure most WGT players do use the "putting target" to putt.......but, it you don't place the target just "right"....and you don't hit the correct distance for a given putt....it won't go in.
I admit, my putting is NOT that good. I'm just under 40% on my (1 putt average). I'm a Legend with a 65.35 average....hit 1,800 ranked rounds now. But, in all of those ranked rounds....I have NEVER used putter pal OR the putting target. I just read the putting grid and putt. I realize I'm guessing a lot on putts.....but, so are PGA pros and so is everyone on WGT who uses the putting target.
I think....whatever method works for you, use that method to putt. I will say this...I do use that TARGET on my other golf shots......just not when I putt.
