The maths behind it is still beyond me! I'm hoping to find some kind of simple guide for it.

think of the punnet square used to describe the chances of a baby having blue eyes ;-)

Yes it is very similar! What I find hard to get my head around is the statistical analysis and the pure maths style expressions which are used to describe them - the matrices - which are really just tables are not a problem.

Please share it as soon as you get it!

I will on my side try to write down some explanation about the other problem (gold and special relativity) we chatted a bit earlier today.

Will do I just hope I'm not too far away from my pure maths days to understand it. Most of the papers I have read just go straight to the complex stuff! I'm no John Nash lol!
