You guys are starting to sidetrack. The question was spreadsheets, rulers for moving the marker( that the spreadsheet tells you where to put it, protractors that tells you the clock hand location, now a ruler to tell you the spin dot location. Stopwatches to time the dots, to put that avg into a spreadsheet that tells you where to put the marker on the green to make the putt.
Do you think this is the intent WGT had in mind to play the game?
The problem is you say cheat, and the first word that pops in your head is an auto dinger.
You have guys that have been here for 7-9 years , and now you have guys that been here 1-3 years keeping up with them. Something is not right, and I think it is due to all these aids that are available.
Of the things you mention, the only one I see as a possible violation is the stopwatch timing the dots. A real life professional player who plays the same hole over and over will eventually narrow down his target almost to the blade of grass he wants to hit. He picks the specific target with the aid of his notebook and experience.
I'm sure the founders of St. Andrews never had in mind the GPS, rangefinders, high-tech clubs and balls, etc., etc. of today. But, they exist and they're accepted more and more. Yes, those aids get somewhat limited by the powers that be from time to time but things are still light years ahead of what they were when the game started. Some people call the innovations to play better cheating. Others call it progress.
Because of technological improvements a larger number of people are much better at scoring in real-world golf, too, when you only consider the very top players. PGA leaderboards are now crowded and many of those names are relatively young and inexperienced compared to the leaderboards of yesteryear.
For the average low-level player who just wants to play a game and be entertained, however, all these aids are really no big deal.
