Is 1-2 big ships per patroll good?

The biggest drawback with the stopwatch-speed calculation is that in order for speed to be accurately calculated your U-boat must be at dead stop and your target at 90 degrees AoB. As the AoB becomes more acute, then speed will seem slower; at 0 or 180 it'll appear 0 knots. And since the speed calculation is essentially using trigonometry to calculate speed, if your U-boat is moving at all that buggers up the calculation too.
