Oh? I don't think so. You may get 8 PIE average with premium-top-notch media only, like YUDEN000 T02, maybe wuth MCC004, but that's about it.
philipshu has it right about NEC PIE (magnifying) , but also not all units scan the same, and sometimes you have to scan @12X or @8X, yes I know the "official" speed is 5X but not all units "like" this scanning speed, my unit "likes" 12X much better.
I also think that this is a good scan for average CMC media. You drive is not to blame here, try better media and you'll see better PIE levels. But this scan above is nothing to worry about IMO.
