Mmm, it's really hard to evaluate without seeing EO or KC3K data because air battles are so full of RNG, it's actually easier to judge setups through theory than looking at emperical damage results.

For instance, say in a bombing pass there are 3 bomber slots. Each slot has a 33% chance of getting the minimum shot down by enemy fighters, 33% chance of a middle number shot down, and 33% of getting the maximum shot down. Each slot also has a 25% chance of not getting shot down by enemy AA, 25% chance of getting shot down by proportional AA, 25% chance of getting shot down by fixed AA, and 25% of getting rekt by both proportional and fixed AA. Then there's a critical chance to obscure things further, and also a pretty high chance to miss altogether. Each of these bomber slots has RNG targeting, and it's hard to tell what happened when two planes target the same slot. There's so much variance that even the worst of setups can do spectacular damage, and the best of setups can fail horribly.

tl;dr anecdotal evidence for land bases doesn't really mean anything unfortunately
