It is interesting, but I think flawed. They need to have the Rancor in there to see what happens when people begin to withdraw their support (which will happen if people think it is going to fail or not unlock the tiers they want etc.). I can't remember when the others crossed the baseline - but I think it was well before the end date and once over more people piled in. In this model it won't get base funding until 24hrs before the end, not long enough to get much more support, also if it goes that close to the wire, I think people may pull out because they don't want to spend the money and not get everything.
Whatever happens this is a poor performing fund (I have now fully decided to leave it alone...).
