The hole-by-hole stats will help once available. But we already know that the SSA from using buncr everywhere this year is about the same as 2008 and 2009 when buncr was first used but several holes had throw & distance (T&D) penalties. That would indicate buncr this year was equal to T&D then and T&D is more punitive than normal OB.
Here's a good example on the top card yesterday. Nikko teed with a roller on #8 that went OB, then went with a power anny drive that burned OB after hitting the ground. Then he ripped a line drive down the center that barely stayed inbounds. With regular OB rule, he would have progressed down the fairway lying 2 after his tee shot in about the same spot he was lying 3 yesterday with the buncr rule.
With regular OB versus buncr, buncr is going to increase scores a bit when the places players go OB is near the end of the flight like holes 3, 5 (first two throws) & 8 because they can't escape executing the shot until it lands inbounds and it may take more than one more try. Regular OB may be a bit more punitive if the OB is near the start of the flight path like 10 & 13 although the big arms that try the direct route on 10 can end up OB after crossing some IB near the pin and would get to move forward.
Rater of the tossed arc.
