See the full methodology for how each piece is calculated.
This trader's average return across 53 resolved positions was -14%. Sirtio Score doesn't use that raw number directly -- it's first blended toward the average trader's return, proportional to how little or much track record exists for this wallet, then measured against how uncertain that blended estimate still is. A thin sample or an inconsistent track record both widen that uncertainty and pull the score toward 50 (breakeven); a large, consistent sample lets the score move further from it in either direction.
