TailMyPicks grades a pick on the market’s winning outcome whether or not the wallet sold beforehand — buying the winner at 40c and selling at 80c is still a correct forecast. Backed is the side left once opposing buys cancel each other share for share, so a fully hedged market yields no pick at all.

Every figure here describes what TailMyPicks scored — positions held to resolution in markets that cleared the thresholds below. It is not a Polymarket account balance, and open positions are not counted anywhere on this site.

One call is not a record. Here is this wallet’s whole Tennis record.

These 7 columns describe every qualified pick this wallet holds in Tennis and say nothing about the market above. vs expected is the number of wins over what the prices it paid already implied, which is what separates a forecaster from somebody who bought favourites.

From here

Not every trade counts. A Pick has to clear four thresholds to be scored.

TailMyPicks scores a wallet on what it can actually be judged on: positions held to resolution, in markets with enough volume to be real, at prices where being right was not already priced in.

  • The market traded at least $500.
  • The entry price was between 0.00 and 0.80 — a near-certainty is not a call.
  • The position was at least $10 — dust is not a position.
  • The market has resolved, so there is a right answer to grade against.

Thresholds behind these numbers: set by an operator decision, not measured.
