Torpedo spreads?

[MarkShot]

In the WWII sims I have played, there is a gyro offset control on TDC to get a spread, but nothing like that here for SC/DW.

If you input snapshots, but then the relative motion of your target is ignore by fire control when the weapon is launched. This can introduce considerable target drift on a long range shot.

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.
