I always calculate target speed (and course/aob) myself through tracking but check it using the option on the TDC (which through comparison also indicates the quality of my stadimeter range readings.) I.e, if the clock icon course/speed is close to my pre-calculated course/speed, that indicates my stadimeter ranges can be trusted.
I wouldn't use the 'Estimated target speed' button (little chrono. icon) on the TDC as it doesn't take averages into account.
This video more or less shows the flaw in it.

I guess I like the tracking and hunting part of the game, plotting and messing with the dials and creating and refining a targeting solution until the moment of truth. Putting a torpedo exactly where I want it (e.g. at the stack, or under the main turret) is the best part of the game. The TMO uber AI sort of wrecks that for me. There seems to be a prevailing mindset on the forums that if you don't like the TMO AI, you will once you get better at evading. You can even use TMO with training wheels if the AI is too tough. I like pretty much everything about TMO except for the AI. If I still don't like the AI, I guess I never will. I was wondering if there was a silent majority out there that feels similarly.
