Thanks, unfortunately the values mean nothing to me (1.25% per convoy vessels or per convoy?, 1.25 units? Etc etc) so i can only guess at the mechanics. So below is complete guesswork:
this assumes that every one convoy vessel sunk is a 1.25% loss in efficency.
if it is 1.25%, and I stack say 10 sub fleets of 6 subs that only destroy 1 convoy every engagement (each) theoretically that’s about 12.5% (10 x 1.25) efficiency loss from multi stacking.
then take away 0.04% per day means only a real loss of 12% a day In convoy efficiency.
bearing in mind that the subs are out constantly every day unless completely wiped out or back for repair (which is rare with high level subs) that means an average of losing 12% convoy efficiency every single time an engagement occurs with every sub fleet and 1 convoy vessel is sunk.
this is where too many variable come into place; this maths assumes that all 10 sub fleets will engage every day and sink at least one convoy vessel. then we have to take into account the frequency of convoy engagements, which could vary significantly dependant on doctrine, location and technology, and I simply have not used subs enough to know their average engagements per day/week/year with full sub naval doctrine .
so this is the worst case scanerio; by stacking 10 small fleets and getting at least one engagement each day from each fleet and sinking one convoy vessel each, within about 9-10 days (10 x 12%) I will have brought the convoy efficiency to 0.
this absolute poor conjecture however if it is right this means then submarines might be a tad overpowered.
now, using the same assumptions, we put all those small 6 sub fleets into one big fleet, so 1 fleet of 60 subs. Now let’s assume that these sink the same equivalent in convoy vessels as the small fleet strategy (10 convoy vessels). That means every day they engage a convoy and sink 10 vessels per day, so a 12% damage to resource efficiency. However, and this is a big however, as all the subs are in one big fleet, they should be easier to intercept with ASW vessels, meaning that the sub fleet can’t expand as much over territory and are more likely to do less damage/ lose more subs) Per engagement.
again, too many variables, however you can take an educated guess and assume that the larger sub fleet will be less effective then the smaller sub fleet, as the smaller fleets will be less likely to be completely intercepted by asw vessels.
again, this is just me guessing and pure conjecture, if someone could provide the actual % loss per convoy vessel lost then we could work out the actual maths
NOTE= I have never seen a complete loss of resource efficency in 10 days, so the maths has to be off.
