Recorded before kick-off: supporting evidence

Eligible price: a market price that meets the price rule of its part of the record; the return is calculated on picks with one. Definition.

How the market price is set

Recorded before kick-off, graded after the match

2 predictions recorded before kick-off. Right in 2 of 2.

Prices implied by market

By market: Over/under goals 9 of 16 (prices implied 59.1% Small sample (16)); Match result 8 of 13 (prices implied 61.3% Small sample (13)); Double chance 5 of 7 (5 W / 2 L, average odds 1.33) Small sample (7); Both teams to score 1 of 3 (1 W / 2 L, average odds 1.79) Small sample (3).

The implied share is the average of 1 ÷ price; it includes the bookmaker margin, so it is slightly above a fair chance. Markets with low prices are won more often, so a share of picks won says little on its own.

An author-quoted price is the price the article offered; the headline return uses the market price in the last column.

What kind of number is this?

Measured

Settled by us from the final score. Supporting evidence: Directly observed in a source or timestamped capture. Here: the moment we first captured each prediction; our pre-match market snapshot of each settled pick.

Stated

The author’s own claim, shown as published. Reported by the source; not independently confirmed. Here: the publication date a source page shows; the price an author quoted.

Calculated

Derived from the listed inputs under a published rule. Here: outcomes against the final score; returns, intervals and the share of picks won.

Unknown

Not established from the evidence available. Here: nothing on this page.

Stated price vs market

How the prices this author stated compare with an independent market price of the same selection. Calculated from the picks where both prices are known; a gap can come from market movement or from one bookmaker offering more than the market, so it describes the stated prices, not the reason for them.

Our market price when we first recorded the pick — our market price for the same selection when we first recorded the pick (median of bookmakers in our price feed; failing that, the first price within 2 hours after, always before kick-off). Difference = the author's stated price ÷ the market price of the same selection − 1. A pick counts as above the market when the stated price is more than 5.0% higher. Each basis is its own comparison; they are never added together. A pair whose prices differ more than twofold is marked “price disputed”: it is probably not the same selection, so it is left out of this comparison and of every return at the author’s price until a manual check confirms the price. A price that the quoted text does not give is marked “price disputed” in the same way.

Largest gaps: 1.11 against 1.98 (−44.0%) · 1.77 against 1.67 (+6.2%)

How this return was calculated

Every settled pick in “Recorded before kick-off, at our recorded market price” is a stake of 100 points at our recorded market price, a pre-match snapshot of the same selection. The net result (−174.48 points) is the sum of the profit and loss of these 39 settled live picks; the return is the net result divided by the total staked (3,900 points), void picks excluded.

Other prices of the same picks are compared row by row in each part of the record above; they are never added to this number.
