All I can say is start playing without the spreadsheets, for the Tee, and approach shots, lose the protractor, and the rulers, and the spreadsheet for telling the break on the green. If I am wrong, then I am sorry, but I don't think I will be.
Calculators, notes, mapping of clubs, wgt shot pal and wgt putter pal are all ok to use.
One more thing make the shot in a reasonable amount of time. Like 60- 90 seconds
