        actually, just checked, it was 17%. If you have a look at these graphs http://www.vxronline.co.uk/forum/showthread.php?t=98436 you can see there was a difference of about 15.8% which is in the general area. When you start seeing graphs that have transmission losses much lower than this you can pretty much guarantee that the fly calculations are wrong. You have to also remember that "at the fly" is just a calculation based (hopefully) on previous experiences and other data.

        There is always going to be a loss between the fly and wheels as the power has to travel a distance to get there and some elements of a drive train offer resistance. It's basically similar to electricity, the further it has to travel the more voltage drop you will get.
