4 Bearing method, useless in combat?

[Shkval]

@Pisces & Kuikeg my teachers... just follow their instructions and soon you will hit them with your eyes closed... for a single contacts the 4 bearing method is incredible, my personal record was a hit at 7 Km with a salvo of three (bow, middle, stern) without raising the periscope a single time...

... Nooo! That's a common misconception. Distance to target being irrelevant is only when the Gyro angle is zero or close to it. If you set yourself up being angled 45 degrees across the track (with AOB set appropriately for the bearing) while still aiming with 0 gyro angle, then it is also irrelevant. 90 degrees across the track only gets you his best broadside, and hence best margin of error for speed estimates. Distance is only irrelevant if the torpedoes do not need to turn. The minimum torpedo arming distance taken aside, that is.

I'm not sure what you are disagreeing with. I said:

"At about 5-10 degrees from zero (depending on the speed of your torpedo setting) the gyroangle will hit zero. This is where you need to aim your periscope regardless of distance to target. That is the nice thing about the 90 degree shot - distance to target is irrelevant.

If you are making a 90 degree attack with gyroangle set to zero, distance is irrelevant.

There may be other attacks where distance is also irrelevant, but I wasn't commenting on those.

I tripped over this. I was saying that ANY degree attack, with gyroangle set to zero, distance is irrelevant. Being perpendicular to the target track is not special for that purpose.

Oh, I see what you are saying now. I did not know that.
