Price Identifiers are used to settle the price of LSP tokens. Each APT Pair has its own Price ID linked to the athlete’s statistics. APT Price IDs are an aggregate of statistical data supplied by SportsData.io and made available on-chain by Chainlink Labs.
Price IDs are built to represent the value of an athlete relative to the best replacement athlete. A replacement level athlete is different in each sport; replacement level in baseball is the best player at that position in AAA, in other sports it is commonly the ‘best free agent on the market’.
There are several ways to measure relative athlete performance value. The Wins Above Replacement (WAR) metric is the most developed model for measuring relative athlete performance. The components of WAR are translated into other sports when considering non-baseball athletes. For basketball, this is a combination of +/- and Player Efficiency Rating. AthleteX will continue to develop performance metrics and adjust Price IDs according to community governance.
Wins Above Replacement (WAR) is an attempt by the sabermetric baseball community to summarize a player’s total contributions to their team in one statistic. You should always use more than one metric at a time when evaluating players, but WAR is all-inclusive and provides a useful reference point for comparing players. WAR offers an estimate to answer the question, “If this player got injured and their team had to replace them with a freely available minor league or a AAA player from their bench, how much value would the team be losing?” This value is expressed in a wins format, so we could say that Player X is worth +6.3 wins to their team while Player Y is only worth +3.5 wins, which means it is highly likely that Player X has been more valuable than Player Y.
WAR is not meant to be a perfectly precise indicator of a player’s contribution, but rather an estimate of their value to date. By creating a market for WAR, AthleteX creates a prediction market for the value of athletes according to the amount of Wins they add to their team. Given the imperfections of some of the available data and the assumptions made to calculate other components, WAR works best as an approximation. A 6 WAR player might be worth between 5.0 and 7.0 WAR, but it is pretty safe to say they are at least an All-Star level player and potentially an MVP.
