I fully understand that. What I am explaining to you is that the idea of a VC fund is to create a return by investing money in a portfolio of companies which overall, should create a positive return. There is absolutely no way of knowing going in what the fund will return. If I figure that out of ten investments one will create a positive return great enough to pay for nine others, that does not mean that I am hoping or expecting that each of the ten will return me 10x. Keep in mind that those nine losers are completely independent of each other. If five win and five lose, all the better. If five win and three break even and two lose, that's even better.
If I invest $100 into 10 different stocks, and I figure that nine of the ten are going to be losses, then I hope that one of the ten will return me at least $1000, or 10x my original investment. That's very different than saying that any of the ten that returns me less than 10x is a disappointment. On the contrary, if one happens to return me 10x over the lifetime of my portfolio and another returns me 2x, then I am even better off than I anticipated.
