Differences Between X Scoring System and Flash Collective RankingsOk, so before I go into the technical details of the XSS, a few differences between it and FCR:
- The core difference between the X Scoring System and the Flash Collective Rankings is that the FCR is based off of tournament placings whereas XSS is based off of player-player interactions.- FCR relies on number of entrants. XSS does not.
- XSS relies on set counts. FCR does not.
- Both FCR and XSS have complicated Spreadsheets, but also have a human-readable form.
Basic Explanation of the X Scoring SystemThe X Scoring System is a lot less complicated than it seems. In short, it's just a big spreadsheet of win-loss records between players. Because it's laid out that way, it is very possible to get different rankings based on a certain player than the standardized General Player Average (GPA). Read on to get details on these three elements of the X Scoring System.
The Win-Loss RatioThe win-loss ratio plays a large role in the XSS, so large it is the entire basis of the rankings. As players play each other more, the win-loss records get higher, and by extension, more accurate as time passes.
The SpreadsheetThe spreadsheet portrays the Win-Loss records a certain way. Wins are along the rows and account for the GPA and GPA2. Losses by extensions are in the collumns and make the GPA3 and GPA4 (coming soon).
The General Player Average (GPA) and its Derivatives (GPA2, GPA3, and GPA4)The General Player Average is a standard ranking for the XSS, and does not base off of a single player, but off of all players. The GPA is calculated by taking the average win count of all players fought by a single player. The GPA2, GPA3, and GPA4 are simply derivatives of GPA, with one or two changes:
- GPA2: GPA, with the highest and lowest values removed.
- GPA3: GPA for losses instead of wins.
- GPA4: GPA3, with the highest and lowest values removed.
The Future of the X Scoring SystemThis isn't nowhere near the cleanest system, and honestly I'd be better off using the ELO or GLICKO or GECKO or MLG or MGN system or something. Or I could provide support for this one. I chose the latter, and with my luck there will be an XSS v3.1.
Appendix A: X Scoring System v2.1Formula: [ set(W-L, W > 0, W > L | W-(L-1), L > W, L > 0) + set(...) + set (...) ] / set count / tour count
Appendix B: X Scoring System v2.0Formula: [ set(W-L, W > 0, W > L | W-(L-1), L > W, L > 0) + set(...) + set (...) ] / tour count
Appendix C: X Scoring System v1.0Formula: [ set(W-L, W > 0, W > L | W-(L-1), L > W, L > 0) + set(...) + set (...) ]
