Now, looking at your last screenie -- some time has passed since you made your initial TDC calculations/input. No doubt between the time you entered AoB and the time you confirmed your settings the target's AoB has changed, yet you haven't updated your AoB -- so is it safe to assume that if accurate data is entered into the TDC initially (bearing, AoB, speed and distance) and then confirmed as you indicate, that the TDC is properly updating the torpedo's track to intercept the target?
This is fascinating stuff.

Yes. If the PK is turned on and the solution is correct then the torpedos will use the automatically updated solution based on the PK's estimation. It will update the AOB all by itself, but of course that requires a pretty accurate AOB to be used in the first place.
There is also a method to check your target's AOB without scribling on the map (very useful when the map updates are turned off). When you make the second distace measurement and get the estimated speed, you'll also get the target's estimated heading, based on it's relation to 0degrees (north). On the upper dial on the PK, you'll notice two dials as well. The outer dial is the "true compass" for your target's position (you get this after you measure the distance which combined with the bearing pretty much gives you the position). The inner dial is your target's heading (aka AOB). Now based on the heading you got after the sencond measurement, you can fine tune the AOB by matching the inner dial's 0degree to the outer dial.
On my pictures you can see that the heading I put in was ~98 degrees. So if after the second distance measurement you get a speed of X and a heading of - let's say - 168, then you simply adjust the AOB dial and keep updating the solution until you see that the inner dial's 0 marker is right above the outer dial's 168 mark. At that point you - assuming the measurements were fairly acurate - you'll have the target's AOB without that tedious measuring on the map.
But don't get me wrong. Using the map can be much-much-much more accurate, but for starters, I would suggest you use this method.
There are a few very neat tricks detailed in
THIS thread that does not require the use of the PK. If you feel secure about your manual targeting using the position keeper, then I suggest you start looking into these methods as they can be very rewarding if pulled off correctly.
