Idk where you find these "calculations", in which site or blog or whatever, but really don't matter.
The only thing that matters, is that there is no matrix system.

The "system" that you describe and want to "calculate" how many ppl you want in order to get rich (lol), is a "classic" scam MMM based scheme.
So i will suggest you two ways.
1. Move (to Investors-Based games section) or better, lock this Thread of yours.
2. Stop wasting your time and energy, for something that is just a fairytale/fraud/scam/steal/lie. You can name it whatever you like, it's the same.
