You aren't explaining this very well greyrider, it would help if you answered some of the questions, instead of going on a rant about the plagurism of mathematical concepts that have been around for centuries.

Are you sying that this method only works if the AoB is ten degrees? If it isn't then this method won't work and you just have to try it to see if it does work and then you'd know if it worked (if your torpedoes hit)? If that's NOT what you're saying, how can you just assume that the AoB is ten degrees when you turn to have the target at a relative bearing of 80 degrees? That's a very specific setup, where you would have to be in a very specific place, e.g. very small distance to track and you'd need to be at right angles to his track.
