Very true, and my apologies for not actually answering the question.Thanks for your insights, most of which aligns with what I think myself. But you could have just answered that you don’t use the sort of codified rules I am asking about. I want to hear from those who do, in order to understand how it works for them.

But I will say that in some ways I think the details of why I don't use 'hand economy' do in fact go a long way towards figuring out the kinds of things one would have to consider if they decided to go in that direction. All the issues I being up are the same issues one would have to deal with and account for, whether they do adopt the economy or they don't. Which to me seems it could be just as useful as someone who just explains what they do... especially if what they do turns out to not be that detailed in the slightest, LOL.
But note taken!
