Likely that NGK is trying to protect themselves from shade tree gorillas (and lawsuits).
20% less torque when using antisieze will net roughly same tension depending on grade and size of fastener. Plating may enhance this scenario a bit.
Plating can weaken some substrates, but I don't think it's a factor here. It all about the friction between threads and resulting tension.
61- Bet you could hit 99% within spec without a torque wrench, lubed or not.

i had never used anti-seize compounds
the only tip I played is to clean the thread in the engine head with a circular brush diped in gasoline, and let it dry before installing a new spark plug
thanks for the info
