Well, I like that you are working the game closer to real values. My only complaint is that the settings of 1/3, 2/3, standard, full, and flank should be adhered to. 1/3 means that it is 1/3 standard speed. 2/3 (or slow) is 2/3 standard speed. Standard is self explanitory. Full is faster than standard. And flank is max ship speed. The only problem is determining the settings for standard, full, and flank to match them historically. The 1st 2 settings would be an easy setup from there.

After some research (I can list where I got the doc if you like. and even where to find the info in the dock that matches this info) I find that the telegraph settings should be set to the following. (source is from a NROTC course document. That is Navy ROTC).
Code:
1/3 = 25% of full
2/3 = 50% of full
Standard = 75% of full
Full = 100% of full
Flank = 125% of full 
back 1/3 = 25% of full
back 2/3 = 50% of full 
back full = 75% of full
The problem I have with this source is that it is talking about the telegraph setup for a nuclear powered carrier. Therefore I went into some of the patrol logs (USS Batfish) and compared the numbers a bit. After reading through patrols 1 and 2 without any relevant data, I came across him stating that he was going ahead full (16 kts). Knowing that the Balao class sub has a max speed of 20.25 kts I was able to extrapolate some data to compare with any further info given in the logs. The following is that extrapolation.
Code:
Speed         Surfaced    Submerged      Percentage
Flank         20.25kts      8.75kts       125% Full
Full             16kts         7kts       100% Full
Standard      12.15kts      5.25kts        75% Full
2/3            8.34kts       3.5kts        50% Full
1/3            4.05kts      1.75kts        25% Full

The above give the following multipliers for the Balao class.
(at least as far as I can get from the Batfish patrols)

Flank    = 1.0
Full     = 0.8
Standard = 0.6
2/3      = 0.4
1/3      = 0.2
After I crunched the data above I noticed that it was close to other referances to kts from a telegraph order (at least for the USS Batfish ss-310). If someone knows someplace other than
Code:
http://www.ussbatfish.com/batfish-main.html
where I can read war patrols I will gladly do the research an number crunching to find a good overall multiplier for these telegraph settings.

Cheers,
