:hmm:
The idea behind the 3:15 rule is that it allows you to equate hundreds of meters travelled during that time to speed in knots. If the destroyer travelled 1km in 3:15, that would be 1000 meters/100 = 10 knots.
Congrats on getting the destroyer, though. They are tough to hit because they are fast and shallow. The only times I've been consistently successful is when I let them get within 500 yards, then fire magnetics at them.
Still, conventional wisdom is to leave them alone unless you absolutely have to sink one. The nice thing is that you get to choose.
By the way, get a whiz wheel. They make AOB and speed calculations a breeze:

My preference is for the physical version, but there are Flash and in-game versions available. |
Well, I used the ruler to measure the distance between the points and it measured the distance as 1. Now can that be interpreted as 1000 meters or 1km?? I'm wondering how close my speed calculation was, i can't have been THAT wrong if the torpedo hit
But having said that they were not that far away, so being so close to the destroyer may have been the "saving" factor in allowing the torpedo to still hit the target.
