Need Some Clarification, AoB and TDC

All:

I've enjoyed the treasure trove of info on this board and I'd like to thank all for their contributions. I have read and studied many of the tutorials, especially related to TDC and such, but I still have a slight problem and a few minor questions. If anyone can shed some light on this, I'd appreciate it. here is the order in which I am setting up a firing solution.

I view the target in my scope and lock (L) on to it.
I engage the position keeper (PK); is this too early?
I calculate AoB by using the navigation map and "protractor" -- drawing a line from in front of the target (along it's path of travel) to the center of the target and then to the center of my sub, giving the AoB.
I then enter the AoB into the TDC and send data
I then use the stadimeter(sp?) to calculate distance (the correct shadow seems to appear even if I do not choose the correct ship from the recognition manual) and send to the TDC.
I wait five to ten seconds and use the stadimeter(sp?) again and send to TDC.
I then calculate speed of target on the TDC and send to TDC.
I fire my torpedo (torpedo doors aleady opened).

Questions --

By the time I am ready to shoot, the AoB has invariably changed. Has the PK kept track of this? Is it necessary to update the AoB?
Am I engaging PK too early? What is the PK doing for me if not updating the AoB automatically?
Am I fooling myself by NOT using the recognition manual and making sure I choose the correct ship from the manual and send to the TDC (even though the shadow on the stadimeter(sp?) is the correct one)?

Reason -- My torpedos seem to be way off in their track, I experience a high degree of misses, even at close (1000 yd) range.
