AI Stop-and-Go + TDC Lag

[desirableroasted]

New career, first patrol, August 23 1939, VIIB, GWX 3.0

On my way out of W'haven, I noticed a large merchant on a collision course with me. Knowing that the AI would never let the ship hit me, I kept my course and speed. Sure enough, at about 100 meters, the AI ship instantly went to back-full and -- this was interesting -- paralleled my course (me going forward at 8knts, it going backwards at 8knts, side by side.

For fun, I did a target solution on it. Whoa... the solution was way off. In fact, the solution was for where the ship would have been if it had never done the AI Stop-and-Go.

After about a minute, she bore off (in reverse still), and then the TDC came to its senses and found a correct solution.

Since this was safely prewar, I tried this on about a dozen ships on the way down the channel. I got 7 to do the "Stop-and-Go Dance" and in every case the TDC lagged from seconds to up to full game minute in presenting the right data and a solution.

I think this explains why, when I disrupt a convoy by slowing or stopping ships, I can never come close to hitting a target doing the Stop-and-Go: TDC is giving me a solution for where the ship should be, not where it is, at least until some sort of lag catches up.

Obviously I have not done a controlled test of this. Have the rest of you encountered this?
