Why does Autopilot show Congress Buys Sharpe 0.76 when Quiver shows about 1.12?

They are not two estimates of the same number. Autopilot Sharpe 0.76 (published CAGR gross about 22%, start 2024-04-11, as of 2026-09-03) is the official live composite of Autopilot follower accounts since the strategy launched on Autopilot. Quiver Sharpe about 1.12 (start 2020-04-01) is a hypothetical backtest on Quiver's site, including years before the strategy existed as an Autopilot portfolio. This site does not publish a Quiver CAGR. The gap is window plus live composite versus backtest. Autopilot performance is measured only from the date the strategy launched on Autopilot (live follower composite). Vendor or creator pages may include a hypothetical backtest from before that launch. Those figures are a different series over a different window. Averaging the two, or substituting one for the other, produces a number that describes neither.
