The periscope would be rotated by hand (either by the skipper or the assistant approach officer). The way it does so automatically in the game, is just so we don't have to fiddle with the mouse every second. Same with the TBT; they really work independently of the TDC.

As far as proceedure, I would lock on the target at once (it doesn't matter if you don't, but why wait?), enter speed, then AoB, then range and bearing. Bearing should be last, because it is frequently changing rapidly, and delay here would affect your solution more.

BTW, if it is necessary to look around the area for escorts/aircraft/whatever, I would look around first, then lock on the target and update the TDC.
