When I first started there were far fewer green speed options. Back then you had your power dictated by the name, be it fast, slow, etc etc.
Nowadays the stimp speed can vary regardless of the named green speed.
Sooo... a good place to start is just ignore the named green speed and go purely by the stimp reading shown and divide it by 9.*
Add elevation shown, add a foot or so depending if you ram putts or wipe yer feet before fist pumping the air...
30 foot putt, 6 in up, on Championship greens (14.5 in this example) for me would be:
37 x 0.63 = 23.31
24ft of power
*Young46's wonderful video tips (via YouTube) is the place I first saw the above.
Apologies, just reread the exact title of the thread.
NO I DON'T.
