i read up on some of the convoy approaching tactics some of the sh3 players use here and it seems that many of them take shots from 1000+ meters away from the merchants. i generally set up shots on single vessels from no more than 500 meters using steam torpedoes in day light (merchants seem to spot them and the torpedoes dont make it in time before they change course) i have missed shots at 500 meters because of this. What should be my TDC settings for firing at over 1000 meters? i always set up for a 90 degree AOB. What bearing should the ship be at when i fire the torpedoes so they have enough time to reach their target and hit? Should i get closer if i can? If im using electric torpedoes which only go slow at what bearing should i fire the eels? should i fire a salvo or one at a time?
