Some posts on the various forums have stated that the 90 or 95 and higher VDI readings on iron is actually the iron signal wrapping around to the end of the scale. For this reason, some people will notch out anything 90 or above. Usually, you will only find silver dollars this high up on the numbers. So if you notch out the high end, you will not find that silver dollar that you probably would never have found in the the first place.
I don't pretend to understand this "iron wrap around" business or if it is even a legitimate phenomenon.
