Basically - Chevy, essentially, determined that was a cylinder that was prone to knock (?maybe airflow distribution, just noise from the reciprocating assembly/valvetrain/blower gearset [ZL1s]/etc., or something along those lines?) from some factor (and I think there are 2-cylinders for ZL1s that might have STATIC retard...), so it might be, in some circumstances, to say it's false, but they put those there for a reason. I'm not suggesting anything else otherwise, as each car is different, and combinations outside of OEM will differ even more, but it's probably pretty safe to say ZERO'ing that table out is relatively safe on it's own, but I wouldn't mess with KNOCK SENSOR SENSITIVITY without careful "scrutinization" of everything else.
If you're on OEM sensitivity, and on E', without commanding crazy SPARK ADVANCE - you're probably just fine ZERO'ing that whole table out, or - at least start reducing it until you see if go away. That's, obviously, assuming you KNOW you're on good fuel (or at least high octane - 100 even).
It sounds like you're on the right track though.
