Why brag about manual targetting?

I allow intant targeting in heavy situations - like big storms with rain and fog - but I still do it myself often simply because the computer version always aims for the center of a ship. You really can't get creative with your torpedo shots unless you do the calcs yourself. I do wish there was a way to get rid of the instant calcs in the ingame aiming - such as a delay of 6 seconds and a 5% margin of error.
