When providing AR coating, including the Zeiss Foundation coat or Crizal, are factory coated SRC lenses the starting point of manufacture, or are uncoated lenses the starting point?

In other words, should I be specifying, being charged for, and charging for UNCOATED CR-39 when ordering a lens with AR, or should I add the price of a factory-SRC to the lens and then add the price of the AR?

I believe the former, because VSP does it that way.
