There is another simple way of determining speed..

If you adjust your speed so as to keep the target in one position in your scope (without target lock)

-If you have the ship at 30 degrees AOB and 60 degrees bearing angle, the target speed is 2x your sub speed.

-At 45 AOB and 45 Bearing target speed and sub speed are the same

-If at 60 AOB and 30 Bearing the target speed will be half your sub speed.

These are simple trig relationships that can work with the slower moving convoys. Only problem is that you'll make enough noise for the escorts, if you're going at speed.
