Hi don't know if many people know about this software called DIView for calibrating your hardware for windows find it a lot better than using the windows version much more precise and a lot easier to get your calibration spot on. DIView you can download it from sites like dsd, cst pedals, leobodnar, heusinkveld engineering.... i found this while looking at some top of the line pedals. HERE is 1 link you will find it 1/2 way dwn the page with a you tube video on how to use it... http://www.h-engineering.net/support/sim-pedals-pro/
