You are right. I didn't know that more than one Diamond would profit from a single IBO. This is what you are saying, right? If I, as an IBO, sells something, more than one Diamond will get a piece? Is it because there might be more than one Diamond in my upline?
Not quite the way it works. Bonuses for Emeralds and above are generally taken out of entire corporate profits, not as a percentage of any particular sale.
But that doesn't matter, does it? If Diamonds are, on average, .01% ( 1 to 10,000) then it wouldn't matter. Crank the numbers. One Diamond, 10,000 people -- what confused the matter was that these are average. Certainly there could be a Diamond with only 100 people under them, as long as it is balanced out by another that has 19,900. This is how averages work, right?
Again, not quite. "Diamond" qualification is not strictly sales volume based. It's a recognition of how many separate "silver producer" teams you've developed - six to be recognized as a Diamond. One of those "silver producer" teams could actually be a Diamond themselves, indeed all six could be. Or none of them could be. And strictly speaking once a team reaches "silver" for Diamond, it's no longer "under them" at all, it breaks away, though the Diamond does get complicated.
The basics of the Amway model is volume discounting, but once you get to the top of the volume bonus scale, it does indeed get complicated. In traditional retailing what usually happens if someone you're supplying gets big enough to deal with a manufacturer directly, you simply lose them as a customer. Amway avoids this through various incentives.
So we are back to the original thing I read in the link you provided. With the lack of progress here, I think I understand why it took you so much work to learn all the ins and outs of Amway. It seems like getting a grip on this consists of one step forward and then one back (or to the side).
I think there's two separate issues with understanding Amway. First is that the basic model is exactly the same as normal retailing, just Amway handles the logistics. Unfortunately it's not explained that way. Second is that apart from certain contractual obligations, Amway independent business owners really are independent. They do pretty much what they want when they want. Some of them join together in large groups and work together in a systemised fashion, but there's many of these large groups. You can get to a seminar of 40,000 active, business building distributors in North America and you've still only seen a small part of Amway.
Now I'm wondering how many new IBOs actually learn what they are getting into. Certainly someone would investigate any business they are thinking of signing up with. They may be smarter than you and I though and learn it more quickly. Or they might just trust someone who already knows.
Well this is one of the reasons why legitimate MLMs offer extensive money back guarantees. You can give it a go, learning along the way, for 6 or 12 months and if you figure it's not for you, you can get your money back. At worst (unless you're a complete idiot and alienate all your friends) you've lost some time and gained some experience.
