Okay, should be good to go.
Hello all,
I rechecked the calculations and the calculations for the time to intercept was wrong. It should all work now.
It is valid for where you can intercept (if you can't, the math *may* still work out) and for when you are in a position that the angle on the bow is less than 90 degrees. Again, if you are in a position, relative to the target that this isn't the case, the math on a calculator will work out, but, it will be in error.
For those of you interested in why, it has to due with the domain on the arcsin function. It is restricted to [-pi/2, pi/2]. I will spend more time trying to define this and explain it better in the documentation, but for now, in most cases it works as a good rough estimate for an intercept course, especially once you've closed to visual range and you need an exact course to travel to intercept the target.
Regards,
