I've started trying a new method for lack of a better term called TMA-fudging. Suppose you want to launch a spread of three fish:
(1) Arrive at the correct TMA solution.
(2) Pause the game.
(3) Reposition the ruler earlier on the track by a sufficient amount and enter solution.
(4) Assign fish #1, adjust presets, and command a launch of fish #1 from the NAV screen.
(5) Put the TMA ruler on the correct solution and enter it.
(6) Assign fish #2, adjust presets, and command a launch of fish #2 from the NAV screen.
(7) Reposition the ruler later on the track by a sufficient amount and enter solution.
(8) Assign fish #3, adjust presets, and command a launch of fish #3 from the NAV screen.
(9) Fix your TMA ruler and enter solution, unpause, and do whatever you normally do.
What I like about this approach is that the spread will calculate in the target and your relative motion unlike snapshots.
Anyone using this approach?
Thanks.

The idea behind the spread tactic is to increase the probability of torpedo acquisition in the event the target alerts early to the incoming torpedoes (like within 45 sec) and subsequently decides to evade in the opposite direction.
With the earlier MK-48 (I am talking about the analog torpedo) Fire Control would insert an offset spread of Lead 6 and Lag 14, keeping in mind that the weapon will snake as it searched. However, it was also recognized by the Weapons Community that the spread also provided a partial blind spot between the two torpedoes, meaning even if the target had alerted early to the incoming torpedoes and subsequently decided not to evade in the opposite direction, there was a risk that the two torpedoes would completely miss detection opportunities and the target would have a safe haven out of the line of fire.
When the ADCAP appeared during the 1990s, the spread angle was reduced to Lead & Lag 10 degrees. That is, the first fired torpedo would have a 10 degree course offset leading the target’s course while the second fired unit would have a 10 degree lagging offset. This measure reduced the possibility that the target would have safe haven down the middle of the two torpedoes while keeping a reasonable expectation of target detection in the event of early target alert & evasion.
Since Sub Command does not formally recognize these adjustments, my recommendation is simply to steer the weapon after time of fire. Allow the weapon to drive in the direction of the offset for a few moments and then steer the weapon back to its original course. Do this for both weapons and you will have the same spread as you would have with a gyro offset.
I think the procedure described above is too complex and the desired offset can be easily inserted by steering the weapons after TOF.
