That's because there isn't one - that was an unnecesary compication you
added yourself. As the article explains, you are simply trying to make
the
resistance across each radiator the same - you will discover which ones
have
the most/least resistance when you take your first readings.

It's not somthing I made up myself. I have looked at various sites and
there is conflicting advice this site for examples says you should balance
the radiators working back to the boiler
