“On the right is a factorisation which is mathematically trivial and looks like it just makes things more complicated. I’ve taken the expression on the left and added in a load of things which cancel each other out. But I hope I can justify this decomposition by virtue of it being easier to interpret and measure. So I’m going to present the case for why I think it is.”
Do let me know if you’d prefer something different to that :)
I’ve now changed that section to:
