I don't agree with this statement at least with the putter I have (the gold one)
It is true. When you are within 8-10 feet and hit right on the bar, it calculates your put from the center of the hole, and not from where you are aiming.
There is a lot of glitches like that in the game and this is why it is beta. I am still having fun playing it but there are so many inconsistent behaviors.
Very difficult to improve after you met a certain level (whitout purchasing) because you can't be right on some shots. Distance you have can't allow you to reach the greens in regulation, even when you hit on the bar you are not always given the deserved distance and line... Very frustrating :) but fun and challenging :) just don't expect to improve!
