How did I miss?

[XLjedi]

Missed again...

I'm trying out a new manual targetting tactic in a Porpoise class. Fairly simple, just using the TDC only to find a solution.

I'm using the 1.5 vanilla install.

I'm sitting still in firing position at 1000m (I have metric turned on) and I have already timed the target at a perfect 7.2 kts. I've sent the following info to the TDC:

1) Speed 7kts
2) AoB 90°S (target is approaching from the left)
3) Distance 1000

I have map updates on and I know all of the information is perfect... now I open tube 1 and wait.

When the scope is filled with a target and it looks like a perfect 90°S AoB, I click the send info button (and say "Mark" in my head). Fire1, Open2, Fire2, Open3, Fire3.
I goto external view and the stupid fish are clearly on track to miss astern???

Now in this scnario I'm deliberatly not putting my sub on a 90° beam to the target true course; but I'm not at an extreme gyro angle either, maybe like 110-120°. The fish should swim out and make a gentle 10-15° left turn on to the solution track, but the stupid things are turning too far and missing astern!

I know I have the right distances and I've sent the data to the TDC as the target enters the 90°AoB view at 1000m. Is there some sort of glitch or something that I don't know about? ...related perhaps to the TDC not using the right torpedo speed or maybe having metric turned on?


Update: if you read thru the thread you'll find out that the answer is: You have to click the send data button twice!
