TorpX, I agree with you completely. I'm just using your comments to elaborate and expand.

Absolutely true. Steinbeck, I can understand your outrage, especially since SH3 made it so submerging and then recharging extended your range. In actuality the engine that is doing the recharging is doing so at full speed. it burns more fuel than just staying on the surface. Outrageous or not, it is accurate.

This certainly isn't true with ISP, and I don't know where this idea came from, tbh.
It comes from TMO. Ducimus argued that since the surface fleet cruised at 15 knots and the big American subs were called "Fleet Boats" because they were expected to cruise with the fleet, then Ahead Standard should be the norm. What gets left out is that the surface fleets refueled at sea constantly. Fuel didn't matter, speed did. Fleet-type submarines were indeed designed to operate under those conditions, but never actually did.

It really doesn't make sense. Best mileage will be at one engine speed, which is 'Ahead 1/3' in ISP. The game doesn't care about telegraph settings; you could make 1/3 100% of your max. speed, if you wanted, but it doesn't change your mileage. 9 knots will still get you farther, whether you call it 1/3 or something else. To put it another way, the engine telegraph settings are a matter of convenience. They don't change the engine workings.
Within reasonable bounds the slower you go the less fuel you use. Your car gets better mileage at 35 mph than it does at 65. That's fine on paper, but do you really want to take 20 hours for a cross-country drive instead of 10? It's a compromise. You use the speed that will get you to your patrol zone the fastest and still use the least fuel. Too slow and it takes longer to get there than it's worth. Too fast and you might not get back.
