Flip 1000 pennies and calculate the results enough times and you&#x27;ll get a gausian curve. Some results will consistantly flip heads the majority of the time.<p>It&#x27;s harder to model with VC&#x27;s because they are measured in rewards that get exponentially better with success (money) and are self-reinforcing (better deals from recognition). My guess is that they figured out how to eliminate the absolutely horrible ones and got lucky enough times to have the best deals come to them.
