Hey pyramining,
I think you should really improve the FAQ on your site!
In particular I find this sentence misleading:
30% of your income will be sent upwards: 15% of your income will be sent to your sponsor. 7.5% to the 2nd grade sponsor and 7.5% to the 3rd grade sponsor.
You do not specify this operation happens RECURSIVELY so:
First level sponsor gets only 70% of his 15% revenue = 10.5%
Second level sponsor gets 70% of his 7.5% revenue plus first level revenue on first level revenue = 70% x (7.5% + 15% x 15%) = 70% x 9.75% = 6.825%
Third level sponsor get more than second level one: 70% x (7.5% + 15% x 9.75% + 7.5% x 15%) = 70% x 10.0875% = 7.06125%
Fourth level sponsor gets 70% x (15% x 10.0875% + 7.5% x 9.75% + 7.5% x 15%) = 2.3585625%
And so on...
You should also specify what you mean by "Current infrastructure" and "New infrastructure" so people stop asking the same questions again and again
The % coming from the referrals actually _is_ an income, I thought it was quite clear. However I will try to improove the FAQ section, thanks for the hints.
