My most profound observation is that while I am playing WGT on my MacBookPro running HighSierra 10.3 --- that none of the putting interface tools he shows are in my game. Especially the icons above the putting stroke.
That could be . I don't know about Mac's . But I can tell you that the dozen or so techniques that Tek describes in ver . 1 & 2 .
Tekoma's Putting Techniques vol.1
Tekoma's Putting Techniques vol.2
Are his own observations and creations . Over time you , anyone can utilize and blend some of those . With some of your own observations relative to your own putters , etc .
I also suggest visiting the forum Country Club Corner.
Where there are 100's of CC's with dozens of GR8 players in each one . All anxious and knowledgeable and happy to help and discuss and play with you . Giving you the most valuable access to the greatest key to success here . The WGT CC experience .
Edit: fix the links .
