You are cool.
But you take the wrong subject for your efforts. Investment market's behavior is far more complex than just a simple analytical curve with a bunch of least-squarable parameters, and even if it were then people who found it first would swim in gold, and the market would soon change its behavior.
And yes, these 3 years have changed everything dramatically (mostly destroyed) and I don't think findings for year<2020 are now applicable.
