It occurs to me that tonnage is not that meaningful without the year and the submarine that pulled it off. Pulling 50k in a IXB in 40 is totally different than pulling 50k in a VIIC in 45.

Maybe we can normalize our tonnage by the number of torpedoes on the boat when it left port?

Tons Per Torpedo (TPT) = Patrol Tonnage/available torps.

So, for a VIIB that leaves port with 14 torps, its TPT on a 50k patrol is
50000/14 = 3571.

For the IXB that leaves port with 21 torps, its TPT on a 50k patrol is
50000/21 = 2381.

This obviously doesn't address the differences in difficulty that hold in different years of the war, but it attempts to correct for the loadout of different subs. Thus, a Type II can still have a great TPT but a low overall tonnage.

Secondly, it doesn't address deck gun kills. However, with NYGM tonnage war these are so hard to get that it should only bias the TPT slightly (i.e. 1 or 2 DG kills per patrol, which were already torpedoed anyway).

Third, it might be neat to think about a way of incorporating patrol length into the equation. The idea would be to somehow correct for extremely long patrols where one cherry picks for large tonnage in an unrealistic way. But maybe cherry-picking is part of the fun?

And, it's not obvious how to normalize for difficulty settings (%realism). This would be a good thing to add (since settings like 'dud torpedoes' makes a major difference to tonnage. Maybe something to think about.

Finally, TPT assumes that you fired all your torpedoes. Otherwise, the best way to get a high TPT is to get 1 lucky shot on a KGV and then go home.

Anyway - so what's yer highest TPT?
