Do you know about how much of an artillery spotting improvement there is between AS+ and AS?

While i do end up with around 1-2 bomber slots in total that are 0'd by the end of the run, it is possible to get AS with 2 bombers per CV/L and on the larger slots. I also did a study in the past that showed that even if a bomber slot is 0'd, that your shelling strength is unaffected assuming you can shell off other bomber slots. In the event that both bombers on a CVL are 0'd then you're of course out of luck.

While it is indeed much more bauxite expensive, I find the extra punch helps minimize the rng of node C torps or occasionally blowing up enemy CV/L on the air battle node. Carrier shelling on the boss node is unfortunately chip weak vs. the heavy armor, but crits do happen and are welcome.
