I don't know about this Kat thing...and this thread is kinda old...but if you are looking for a great wind speed calculator, or a putting calculator, Gary Pinhunter is who you want.
Just use google and search GaryPinhunter. He has a website that has tips for many of the courses, written by some of WGT's greatest golfers, all compiled in one place. He also has a downloadable calculator which uses excel.
You should have no problem finding it or using it, it is very simple and accurate (at least the putting one is, I never use a calculator for anything else (and if anyone asks, I do not use a calculator at all).
