Great video. You did an excelent job of showing effects of backspin. I love the chart with the Red Lines.. it clearly shows how the angle of impact is so much different.
Thanks, Champ. Very instructive. Could I ask how you adjust for a long approach shot to an upsloping green and a downsloping green. With an upsloping green (eg, 3 feet rise from front of green to the pin), I am usually short. Should I increase distance or use top spin?
I use the same formula for all approach shots except my 64 wedge club, for my full shots and punch shots, I use half the slope when its uphill . For example, if the green is 10 feet up I only use 5 feet. This video is more on using full backspin for hi up greens instead of just using a little backspin due to the degree of slope and how hi the ball goes in the air.
What is your true distance at 17:15 hole 2. The approach formula calculates to a distance od 82.62 with tw at 50% up elev adj. at 35%*17=5.95....Thanks ...
72 yards 8mph tw at 45% and 17 up elevation comes up to actual shot distance of 76.80 yards. So it would be 72 times 8 is 576 then since its a tailwind you take -225 divided by 45% which is -500 then 576 divided by -500 which is -1.152 then you take -1.152 minus 72 which is 70.848 then you take the up elevation time 35% which is 5.95 then you add the 5.95 to 70.848 which gives you the actual distance of 76.80
Just found this, love it. Thanks

Thanks. I made the graphic because it was much easier to explain with a visual.
