Also, it is very easy to do the math using % , very difficult using degrees. This may change, there is still talk of bringing out a model using %.
Most of the people on the various Tours who use this concept, (the # is growing every week) use % because, lazers are not allowed for shots in Tour events and being able to do the math quickly is critical. Interestingly enough, Jim Flick was asking about this same issue at the John Deere on Tuesday.
One final point, how tight do you want to be with your numbers; when I do a new course I use reflectors to check yardages because the varience with reflectors is very tight ( plus or minus 1 yd). Just shooting a flag or a bunker, the varience is probably plus or minus 3 and therefore your slope yds will also be affected
Hope is helps, if not, I'll try harder

It should be known, and OK is too modest. OK introduced the clinometer to golf. He found the instrument and worked out the correlation of percentage to golf shot (he did have some help with this). There is some difference in the effect based on the club being used and the trajectory. It has become a standard piece of information that players want. My personal opinion is that the most important piece it yields is a hard number instead of "it's 150 yards plus about half a club," it becomes "150--up 4% = 156 total."
He also consulted with and product tested for Bushnell as they introduced their version.
