I thought some of you would appreciate this.

I did a test on a VIIB w/stock engines last night in search of the setting I want to use in NYGM 2.0 and created a table at

http://members.bellatlantic.net/~vze33y78/VIIspeed.htm

My criteria for selecting what I did was:

1. Ahead slow needs to be slow enough for Silent running to be silent, or < 2.0kt. I was tired of doing it manually. Surfaced it just need to be enough to provide steerage.

2. Ahead standard simply needed to be the most efficient speed surfaced.

3. Ahead 1/3 needed to be fast enough for quiet depth changes submerged or > 1.9kt. Surface just needed to be "no wake" speed. It was a nice bonus that it turned out to be exactly 1/3 of Full throttle.

4. Full - exactly double standard, or military time, double time.

5. 100%

I did not test charging times for non selected speeds because it was not a selection criteria.
