Mark Minervini's gains relative to S&P500 during 2021competition

I came across some data which enabled me to construct a chart showing Mark Minervini's monthly gains in his spectacularly successful 2021 trading competition win. I also measured the equivalent monthly gains of the S&P500. My aim was to study how he performed relative to the monthly Index movement so that I could, perhaps, understand his methodology. I have to say that it didn't live up to my expectations as it was hard to see the relationship in some months. I wondered if there was an overall competition winning strategy behind the performance of some of the later months. Jack Corsellis also has helpful looks into specific buys and sells with the actual charts of various transactions of the 1997 competition, that Mark Minervini also won. www.youtube.com/watch?v=yyWfLBgr... .
