How does Igor Beuker prove his prediction record?

With my PAR, Prediction Accuracy Rate: 84% across 25 years of public calls, benchmarked against Morgan Stanley's 46% and Ray Kurzweil's 86%. Every call carries a year and a number, and a wrong call stays on the board, that is the rule. And with 5 exits and 24 social startups: I bet my own money on my own calls, and the exits paid.
