There is also another interesting quirk showing up here. It might be the wind or the hard fairways at SA but try the same test at BPB-I used the 10th fairway and caught a 2 mph win in practice mode. With the free ball the club nails that yardage, very consistently. With the SD ball it picks up a yard or 2. Interestingly enough, with that 2 mph wind pitching against it got 37 and with it got 41.
I went back to SA and sure enough your numbers are right on. It was hard to get a low wind condition there but with a 13 mph tailwind I was able to get in the fat part of the fairway and chip side ways to turn it into a crosswind. Your numbers still held up.
I mentioned the punch shot but neglected to say drop down to the 64 wedge. That's where the 41 yards came in so instead of pitching with the set wedge to get 39 drop down to a 64 wedge (41 yds) and back off the swing. It doesn't roll as much. I did the same test at SA and the punch was consistently 41 with a full swing.
Apparently the fairways at SA are really hard and the ball rolls quite a bit. Not so at BPB!
