According to them, the actual breakdown is:
4.1M total
-2.7M from the 50/50
-1.4M other
--0.3M from direct donations
--1.1M from the special events
(with some rounding errors).
Of the 1.4M
donated, without the 50/50, there is 1M spent on operating. So 0.4M of it sent to the charities. 0.4M/1.4M=29% and it's where they get the 30% from. Of course this assumes relatively no operating cost for the 50/50. But this is actually worse because it accounts for the reserve fund in a round about way.
More or less this foundation is supported by the 50/50 and $300,000 of direct donations. Everything else is just paying for the parties they throw.
