Well it seems to be more or less a version of the probabilistic Sharpe Ratio (ie it doesn't just look at average returns over standard deviation of returns but incorporates skew and kurtosis of those returns). This makes sense and helps to penalise highly negatively skewed, high kurtosis strategies like selling vol.
But yes they should also consider, if not already, penalising high correlation with the s&p500 and high correlation with a simple compounding bank account like structure. That would weed out that #1 account and also penalise many of the leaders which are in effect just long stocks in massive bull market.
