Ah. OK....

So at 700 levels and say 10 million nodes, that would mean that each node had an average of 1.023 children? Wow, that's a pretty strung-out hierarchy.

some are worse than others as far as strung out. Most of it depends on the business model employed. I have seen one tree strung out to about 1200 levels but with only 500k nodes.

Binary Trees in the MLM industry.


Heh... I thought binaries were illegal in the U.S. I thought uni-level was the only legal method for an MLM.

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
If you think its expensive to hire a professional to do the job, wait until you hire an amateur. -- Red Adair

Pyramid schemes are illegal - and matrix, unilevel and binary trees could all be a pyramid scheme. The Fed monitors MLMs closely and makes sure they are in compliance with the law. MLMs and Pyramid schemes are not that much different - just one is legal and the other isn't.

Yep... agreed. And the difference between a pyramid scheme and a legal MLM is a legal MLM actually sells product or tangible services.
