Maximum range at current speed has increased 50%

I use TMO 2.5, so I've checked the most efficient speed (on my Gar it's 9 knots). And with full load of fuel, maintaining speed 9 knots I had maximum range at this speed approx. 22000 nm.
I've already learned that number, so I wasn't surprised.
But, when I sailed from Pearl Harbor at my second patrol, I've measured the same thing, at same speed... And it shown 33000 nm.

I didn't change a thing in the game, didn't install any upgrades on my sub (there wasn't such an option in port). So where did these extra 11000 nm of range came from?

I think the variation is most likely due to when and how you are checking your range at current speed. When you hit the button, the game looks at how fast you're going and how much fuel you're burning, at that instant. This means, if I were to check my range/speed just after I give the order for flank speed from having a much lower speed, I will get a much lower estimate. If I get an estimate while traveling at 20 kts., just after I give the order for ahead slow, the fuel consumption will be low, and the speed will still be high. Thus, the range/speed estimate will be much too high.

The computer has no "common sense"; it will calculate the literal instantaneous value, which is not really what you need to know. I would keep checking periodically (after your speed has reached an equalibrium), and see how it goes. My guess is that your actual range at speed hasn't really changed much if at all.
