I made the calculator myself and the ruler has been around for years. These things do not make you a better player they just cut back on time it takes to play a shot. I can get the same result using no ruler and no spreadsheet but I would play a bit slower. These items are a matter of convenience more than anything else.
For example lets just assume someone has played for 6 years and is a clueless 68 average legend it will make very little if any difference to your game whether you have a ruler or not. If you are happy playing that way I don't see a problem as long as it is fun for you. I would say majority of people on wgt are keen to improve though.
If you think it takes no thought you are badly mistaken lol Go make a calculator that is accurate and do it with out thinking :) Or come up with a way to hit shots that is beyond "I have 160y up 8 ft" If you could you would have already :P
As far as sounding bored while playing..I am not really playing in the video..just trying to show what works for me when it comes to hitting more dings.
Anyway the thread was not intended to offend any anti math people or whatever...I use math and admit it with 100% guilt lol If you are against using math I have a good suggestion...don't use it lol I will be using it whether on a spreadsheet, hand held calculator or in my head.
