Since steps 5 to 7 and 9 to 14 all need to happen instantly, but this isn't really possible, you may need to...

5 to 7 need not be instant, and 9-14 can be greatly speeded up by any GUI mod that adds the TDC controls to the periscope screen (i.e. basically any GUI mod). Allow me to demonstrate with this... improved
version of your method.
1) Set the TDC to Auto.
2) Go to the periscope view and lock on to the target, then
unlock the scope. Between now and step 5
do not move the scope and do not change course.
3) Set the TDC to Manual.
4) The bearing in the TDC will now match that of your scope as it was when you unlocked it (and you have not moved it since then).
Taking as long as you need, and using any method you like (map plotting, whiz wheel, etc.) calculate the AOB that the target ship had when it was at the bearing shown on the TDC i.e. the AOB it had when you unlocked the scope in step 2. Enter that AOB into the TDC, along with the target speed.
5) Set the TDC to Auto. You may now move the scope, but you must still not change course. Go to the periscope and lock it to the target.
6) This bit does need to be done as quickly as possible. Calculate the
current range to the target using whatever method you like. As soon as you have calculated the range unlock the scope, set the TDC to Manual, enter the range into the TDC, set the TDC back to Auto, lock the scope to the target again (or manually aim the scope at the part of the ship you want to hit) and fire.
