Well, that clarifies things quite a bit and does seem quite testable, but I doubt you will find much difference. Already, it's known that with no interceptors in play the first slot (if it exists) is the only one damaged by enemy raids and the damage occurred is from 1~4 planes if over 50 damage is taken in a single raid. So, even if a reduction exists you are talking about trifling fuel/bauxite savings. If the pictures Zel linked are supposed to be any evidence he's probably conflating enemy anti-bomber/AA damage with enemy raid damage.
