You don't need a complex analysis to work out that if you offer stakes aligned with what clubs earn, then you have a sustainable business. It's how the world works. Most of us and most businesses can't buy things or spend money on things just because we think we need them, a few governments and councils aside We have to also have the revenue to pay for them, or like NZRacing, we end up in the dole queue, hand out to government and anyone else we can find to keep going.
