I think you should set all unescorted sorties to lower priority.
Actually they are all set at lower priority as everything else is "very high". But yes, maybe those last in the South could be set even lower.
It seems that I'm getting more aircraft shot down than during my previous tests (in between, there was a couple of patches). Now, I've seen a few interceptions and, sometime, escort don't even prevent bomber losses - it's not a dramatic loss rate but I certainly had better overall results than that previously.
The good news is that it's certainly possible to improve those ADs by a good margin.
