...I just wrote a loooong post about a test I made using the MaGui "x" values...with conclusions, possible things that could be going on, etc...
The post got deleted after I tried to post it because my login expired (why didn't I save the post like I always do? XD)

Well, long story short: the MaGui "x" values from those tables don't work.
They produce the same result as the placement of the red "x" mark to the left of the "90" value on the AoB finder. My torpedoes miss, passing right in front of the target's bow... the shooting bearing they give is too wide.

On the other hand, my custom "x" value hit the target...however, it missed the precise spot I aimed for by 2-5 meters (behind it, so that means the "x" angle should've been slightly higher, but not nearly as high as the MaGui's "x" value).

I performed the test in a way that both shooting bearings could be verified within seconds from each other (by firing two electrical torpedoes).
The first torpedo was launched at "MaGui's shooting bearing", the second torpedo was launched a few seconds after, when the target reached my "custom shooting bearing". As I said, MaGui's value was off by a few degrees, my custom value was off by less than a degree.

Tomorrow I will perform further testing to make sure this isn't an isolated result, if it keeps happening, I'll post the results and possible explanations I see.
