I could be wrong, but I can't see the 4 bearing method being used. IIRC, it is essentially bases upon determining a Spiess line - something that wasn't figured out analytically until later - Spiess's paper wasn't published until 1953.
An easier method is to directly use blade count to determine speed in combination with a bearing / bearing rate plot and fitting the range to the lines of bearing based upon how long the distance between them needs to be for the given speed. Accurate enough for ranges we want to be at for our attack. And when visibility sucks, you can race to an attack position on the surface before submerging again to pick the target up on the hydros.
Much easier than trying to guess a locus point for a future theoretical bearing.
