I have previously looked at the amount of aim correction needed for hitting off a side slope, and was curious about how much effect an up or down slope lie had on carry distance.
EXPERIMENTAL DESIGN:
Using Master Clubs, on flat fairway texture, with wind at 1-3 mph against, I built an identical upslope and downslope. Although I do not know the angle of the slope, the Lie Indicator showed red with rapid movement. I hit clubs off of these, still maintaining an elevation difference from the fairway of less than four feet. I also hit balls off a flat lie. I hit enough balls with each club with a perfect/perfect tempo and on the line to get a consistent carry distance (probably + or - one yard).
RESULTS:
CLUB FLAT UPSLOPE DOWNSLOPE
2W 241 241 241
5I 191 191 191
9I 148 142 150
LW 96 89 98
EXECUTIVE SUMMARY
It appears that up/down slope has no detectable effect on the longer clubs that I tried. I was too lazy to find the club where this changes (somewhere between 6 to 8 iron). For the shorter clubs there is an effect, with it being more evident on upslope. It follows how real golf works, with upslope shots being shorter due to more loft, and downslope longer. Since this is a pretty severe upslope however, I am pretty sure that yellow and green slopes have a minimal effect.
