Making lots more sense now, thanks for the detailed explanation. I thought that with method you needed to pick an already calculated lead angle. I had the whole thing backwards.
Dignan mentioned that O'Kane is limited to 90 degree angles. I haven't seen it used at any other angle but I don't see why it couldn't work at any other angle. Especially since the TDC is doing the work
Rocks and shoals' tutorial for his constant bearing method is not quite the same as O'Kane. But it does seem a little more similar than that.
But, as always, im probably missing something.
