This is a feature of the original doctrine as well. AI submarines don't handle gradual inclines very well starting from stock SC onward.
All I have done in the modified doctrine is alter the evasion angle off of the bearing of the torpedo and instructed the subs to always drop an active decoy.
As I said in the readme, this doctrine in particular needs a lot of work, but I wanted to "quickfix" it to give the AI subs SOME chance of avoiding any torpedo, and the result has been to increase their effectiveness pretty dramatically, if you take into account the fact that I just changed a few numbers and swapped one word.
There could also be some issue with the anti-cavitation routines put in the doctrine, but this has been in the Mod for sometime and we haven't noticed any problems.
Thanks for bringing this up though, because there is something that needs to be done to help with this problem.
