Underwater range and endurance

Well, after modding a Sargo to run at a max of 12 knots submerged I found that flank speed wasn't draining the battery nearly as fast as I thought it should, and running all ahead standard actually drained the battery faster than flank and decreased the range. Fiddled with the numbers again;

miles = 2
knots = 25

Then ran some tests;

5 1/2 hour recharge from 10%

2 knots (1/3rd)
70 miles

5 knots (2/3rd)
37 miles

8 knots (Standard)
16 miles

10 knots (Full)
51 miles

12 knots (Flank)
47 miles

The first three make perfect sense, increase from 2 to 5 knots cuts the range almost in half, increase to 8 knots less than a quarter, but then 10 knots INCREASES the range, and flank is better than 2/3rds. There must be other files and/or data factored in here, horsepower and/or drag possibly.
