Question about using the U-jagd

Salute !!!
Here is my method when timing for target speed:

Set my boat course to about 20 Degrees or so to the targets course.

Set my speed to dead slow... (subs cannot realistically hold depth at zero speed.)
Periscope trained at 0 (180 for stern shots).
Only raise the scope for very short period of time, just enough to start the chronometer when the target crosses the wire.

Down scope... pay some attention to the sound man reports as he calls out the target position changes.
Raise the scope quickly and note how far along the ship the wire is... down scope!
When you think the time is getting close, raise the scope just enough to see and stop the chronometer when the wire crosses the stern of the target. Now is a good time to get the AOB. Be quick about it....

Down scope.. Ahead One Third!, Rudder Full Over to get your boat on the attack course. Input the AOB into TDC.

Now do the math or use the calculation wheel to get the target speed and enter it into the TDC.
You did note the target AOB when you did the target stern crossing the wire, didn't you?

The key is to keep observations as short as possible while getting the maximum information from each peek.
