I was playing number 7 on BP and had a 11 ft birdie putt. Hit putt right on meter at 8 ft marks it was downhill. Ball didnt move. Tried again and same result. Finally on 3rd try it lipped out the cup. Same point on meter and hit the line every time. resulted in a 4 putt for double. Any hints on this problem. My cache was clear and meter wasn't stuttering.
