MainzMan:
I have a Post-It note with a bunch of short lines about 5mm apart along one edge. Under each line is a number. I drew the lines on first, went to St. Andrews #10 in practice mode, played to just off the green and hit a bunch of shots using mulligans. The distance the ball went, including roll out, was written under the appropriate line. I used half back spin on every shot and do the same during a round, slight variations for elevation notwithstanding.
It took me about 5 minutes to make, adds zero time to how long it takes to play a shot and works very well.
Job done.
Now that's my level of maths. Learning by doing, hit and hope or whatever you want to call it, it works for me.
Good on Jo for putting the information out there, sharing it with anybody who wants to use it. He certainly has the scores and stats to back it up, and it would certainly make me look twice as opposed to someone who mixes explosives with alphabetti spaghetti let's say, however amusing or confusing it may be.
Each to their own. For some detailed calculations, spreadsheets and slide rules work for others not. For me, more than 10 of something I'm taking my socks off to count and while I'm not known for ripping up courses I'm satisfied. I just can't imagine after all that math letting rip with a fingerfart on the flop line or woe is me, a meter jump.
If you're interested D, I have a couple of post-its I could make available to download ; )
Happy hitting all, however you choose to do it.
Cheers!
Rich
