Admittedly I have not read every post in this thread, but this is nothing new.
I believe the original discussion that started this was about a program that has been around for a while and is approved by WGT. I've seen it posted on the forums before, you enter in the wind speed, direction, distance, etc. and it tells you what club and what percentage to hit. I can't remember who developed it but I think it overlays on your screen (I have never used it only seen the screenshots). I questioned WGT about this software and was told it is legal, it doesn't slow the meter, hit the ding, etc. but acts as a calculator for you, much as most of us do in our heads, or with notes, or with a real calculator.
The reason some of the players want a 30 second clock is so that you don't have time to do all of this stuff. As always if there are credits, money, etc. involved you can count on people trying to get around the system
