Since you are selling more puts than calls in an environment where vols look to be increasing and market has been possibly tipping over, you might see how well this system does under pressure. As I am sure you are aware, one of those trades popping against you will simply wipe out all your gains. Basically the vanilla selling premium on the indexes which is not reinventing the wheel per se. Always works well in a choppy market like we have had for last two months.
Also, I could never follow a model from someone who claims to be a "Supertrader" and then pushes a strategy basically known to every option trader. Hyper marketing always raises red flags making the strategy seems safer and easier than it appears.
Just raising some obvious caution points from someone who did ICs on the indexes for years and got out well before volatility exploded.
