Hmmm... it's almost like 30+ years of development into digital signal processing from modern detector manufacturers actually makes people's lives better.If I remember correctly, whether they were using zero disc, or disc at around the 12:00 position, didn't seem to have any notable effect on if the coin was hit. The issue seemed to be that with low or no disc, iron falsing would occur. A higher disc helped to mitigate the iron falsing, but then many nonferrous targets would be missed. It was kind of a no win scenario.
