I believe no one algorithm is "correct"; the goal is simply to include as many as you can contribute so we can all play with them.
Yes, now as the weekend finally reached me I can look at it again.
I have looked at third degree PLLs again and if you know where you're
poles should be going, then setting it up is trivial and stability can
