Simplier Manual Targeting Method?

[plymouth]

Hi I have recently started playing SH3 and have been studying the manual targeting method. After a few attempts I noticed its much easier using the TDC screen and just manually adjusting the dials (with the auto update switched off). This way its not necessary to calculate its distance, therefore not necessary to identify the ship, since the target line shows the distance on the map. Also, speed can be set to 0 and the missile fired based on an estimation of the speed of the ship. After a few shots in Naval Academy this method seems to work well. However I don´t know if its 'cheating' and an unrealistic way of playing the game. In GMX 3 the 'Gods view' doesn´t effect the realism (I play at 100%), so I´m only guessing that this method is ok. Does anybody else use this method? Sorry if this has already been discussed elsewhere. Also, is it possible to re-base at another location apart from Kiel? Tks!
