I too have posted negative comments on putting, but I have come to realize, It does change daily and during play!
its not easy and everyone has had there share of WTF putts here or shots !!! sometimes its my fault and other times false reads on my part and sometimes what is shown is not correct either!
You just gotta keep at it, roll with the flaws and remember, ITS JUST A GAME !!!!
Play for Fun not to be the next Tiger Woods or Jack Nicklaus here !
Many try, very few succeed ! Good Luck which ever You decide !
