[sdiy] AD633: Z inputs and W Loops

Hi all -

Apologies for chronic beginner questions -
but I'm working a bit on revising my AD633 ring modulator schematic
and I don't fully understand the relationship re: the resistor from
the W output to the Z output and from the Z output to ground.
I understand that there is some sort of gain addition (+ Z, according
to the datasheet) - but I don't totally understand how to do the math
to determine this gain, nor do I understand how the resistor from W
factors in to this equation.

Hope you are all having productive mornings!
