And FWIW, the place where most of the $$ is made in bonsai-- mass produced bonsai or mallsai--DON'T ADHERE TO DESIGN RULES. They aren't wired, or pruned much. They are plunked in the cheapest smallest pot possible because it's less expensive, but not because of design rules. Mass produced trees are mostly made in China AND ISRAEL, or at some hack nursery in the country they're sold in.
Bonsai conspiracy theories, like the vast majority of conspiracy theories, are bullcrap... No doubt you will find followers ;-)
Besides, no one is making anyone follow the rules, for God's sake. Also FWIW, I too have seen forest groups with even numbers (GASP), I've even seen even numbers suggested in bonsai books from Japan...I've seen trees that don't have traditionally arranged branches and in pots that are too big for them. I've seen trees that don't follow the rules, but work and others that are eyesores...
Follow the rules as you will, or cower in the corner at the cabal of horrid Japanese nursery-enforced mandates, your choice.
I didnt mean to seem aggressive. It was a train of thought. Poorly worded intros cause problems. I was trying to delve into how the angle of efficiency can be applied or may have had a hand in galvanizing these concepts
