Please be sure to set the parameters under which one is to measure the different items to be tested. Such as one aircraft, at one airfield, with or without ground clutter on, with or without clouds/other aircraft in view, etc.
The surtest way to get a level playing field is for you to record a flight and have people make measurements running the very same film.
This eliminates ALOT of irregularities in the different ways folks would interpret how to test thier rig. I'll gladly submit a bench mark after you set the parameters and open the page up.
