BUT, in the pedigrees I'm asking about...
(Bruiser x Belle) x (Ranger x Lil Brook)
and
(Ranger x Lil Brook) x (Bruiser x Belle).
If Bruiser was bred to "Lil Brook" in one of those pedigrees it would be understandable, but he wasn't. So, with the exact genetic make-up why are the WCI's not the same? And I'm not trying to argue, I'm genuinely trying to understand it.

I can't answer your question, because I am neither the creator of the Wright's Inbreeding Coefficient nor am I mathematician enough to explain it to you.

What I can ask you to do is place these same breedings into another (commercial) pedigree program and see if the output is different and then to report your findings here.

On my end, what I can do is ask my brother (a true mathematician) to explain the reasoning to me, if he can, or to correct the mistake (if, indeed, one has been made).

Again, I understand where you're coming from, so hopefully we can find the legitimate answer as to "why" ... or ... correct the mistake in calculation if you've spotted one.

Cheers,

Jack
