I watched it, and I'm disappointed. I find it no more realistic than using Auto Targeting. First, there is no way you can use the periscope for a few seconds and have the exact bearing and range of every ship in the convoy. On the other hand, getting the speed of one ship will give you the speed of the entire convoy. Second, the stated goal is to keep the periscope above water for as short a time as possible. In real life they had to keep it up long enough to gather the correct information. They also had to recheck several times, which meant raising the scope for as long as was necessary. This means that the goal of keeping the scope underwater is contrary to what they actually had to do.

I technically use Manual Targeting, but I use WE Assistance to get the information, but because it's perfect I use it once every two minutes, and I leave the scope up for as long as seems reasonable to me. I use the Assisted Plotting Mod, which only allows you to mark the position of one ship at a time, not the entire convoy. Despite the "perfection" of the WE, I still manage to miss on a fairly regular basis. My way may not be as realistic as full manual targeting, but it feels right to me.
