Well the question is why did you outperform so well initially and then most years underperform? That is the focus to figure out how to correct the system. QQQ had a really bad/shitty 3 years so that hole might be where your comparison makes it look better annualized but year in and year out over past 10 years should be the focus. Also are you outperforming in bearish years because you have short signals and QQQ is just B&H but regularly underperforming bullish years. That might be something to build on....
