Speed not accurate (Using Subschool)

[sgtabell]

In SH4, I am working to make sure my firing solutions are right. I am also using the Grey Wolves mod, everything is up to date.

I am trying to sink that cruiser, and the speed I get back when using the timer is always 5 knots.

My shots are always aft.

Set it to 8 knots, perfect hit.

I have watched the tutorials and think I know what I am doing. (I watch from external cameras).

I take my first mark immediately, I take the 2nd right before I shoot.

Is this a built in delay because I don't open the tube doors or is it something else?

Interestingly, even in SH3 my torps are always a bit aft also...just wondering what I am doing wrong.

Thanks,
