I also have a spreadsheet / cheat sheet that I use when stalking a convoy. It tells me how far the convoy will travel in a certain number of minutes. For example, I can look at my sheet and know that a convoy traveling at 8 knots should traverse 15.8 km in 61 minutes.

Obviously, you could say that it will cover 15.55 km in 60 minutes, but I find the .55 awkward to work with. In reality, the convoy will cover 15.81 km in 61 minutes, but that's close enough to 15.8.

I do hourly checks by hydrophone and typically run 15-20 km away from the convoy (depending on the weather). I have noticed that I often get radar contact from the escorts, but they never wander over to check on me. It's early 1943.
