That is not necessarily true. On average, depending on sub type, 7-8 knots is most efficient. The range falls off if you go slower or faster than that.

What I usually do when I get a new type of sub, if the weather is good, I'll check the range settings at each engine telegraph position(along with speeds) and also at various knot settings to find that sweet spot. I have them recorded on a spread sheet for future reference.
