How do you calculate AOB - Frustrated!!

Success!!

This rusty old fart finally gets it!

One problem I'm having though is speed, each time I have done the Estimate Speed my dial allways shows this ship (Mogami Heavy Cruiser) to be doing 5 to 6 knots.
in the first attempt the speed read 6 knots & the torpedo's just hit the rear end! In the second attempt the speed read 5 knots, I just set it to 9 knots as yours read & this time hit amidships, I tried a third time & the reading was 6 knots again, something is amiss but I don't know what.
This is what I do (I'm sure I got it right):
1) set speed for 1/3rd and hit Z key.
2) go to scope & raise, identify ship, click tick box.
3) lock on, use stadimeter and send to TDC.
4) lower scope, wait for about 1 minute during this time open 4 tubes.
5) raise scope, lock on, use stadimeter, send to TDC, lower scope.
6) go to speed dial & click on "Estimate Speed".
This allways comes to around 6 knots, and I say nuts!

Any idea what I might be doing wrong, can a setting or mod effect this?
Has the Estimate Speed button changed from version 1.0, when I check the SH4 manual page 38 at the top it reads quite different!
Thanks for all your help Fincuan.

When using the stadimeter, are you placing the waterline of the image of the ship at the top of its highest mast?

Do you have the position keeper off while making your two observations? (it looks like from your previous comments the answer is yes)

Are you at battlestations? (I don't think this would cause that much error, but your crew is more accurate in calcuations while at battlestations)

You can also click the Estimate Speed button several times to get different estimates from the crew. You might try that and see if all the speeds are around 6 knots.

Anyway, whatever it is it's something minor. You definitely have the basic idea down.

Oh, one more thing. The Estimate Speed button didn't even work until patch 1.3, so ignore the manual. The way you are doing it is correct except for some small issue.
