Green speed in the open qualifier is a tad slower than champ but still faster than tourney,playing the course in normal stroke play the green speed seems to be dead on champ speed when a tour legend is in the group,no slower no faster.....some players use division to figure green speed distances others use a multiplier I personally use the multiply method distance times .7,,,,example: a 20ft flat putt true champ speed would be 20ft times .7 = 14ft,,,30ft putt =21 etc etc,,keeps me close and in the hole more often than not........
