Total return a bit optimistic

Turns out the next Warren Buffet isn’t Chamath or Sam Bankman-Freid.
According to Sharesight it’s… me!
I’m assuming this is not the case; but if it is I’m open for speaking engagements for audiences with egregiously low expectations.
I am looking for a way to compare my returns with that of a professional fund manager. Is there a selection of settings I can use?
