2010 F-Zero Time Attack Championship FAQ

What is the 2010 F-Zero Time Attack Championship ladder?

The 2010 F-Zero Time Attack Championship ladder is a competition system that ranks players in all F-Zero games based on their best course and lap times.  Each game is counted equally in the total score.  NOTE: F-Zero GX has three ladders - but only one of them is used for each player - the system picks the better score for the player in the case they are in more than one GX time attack ladder.

What is SRPR and AF?

The 2010 F-Zero Time Attack Championship ladder uses two scoring systems to judge player performance.  SRPR stands for site record/player record.  It is a ratio that compares a player's performance against the best times on each ladder.  AF stands for average finish.  AF finds the rank for each record for a player and then divides by the number of records to find the player's average rank for that ladder.

How is the score calculated for each system?

In both scoring systems 0 is the lowest score and higher scores are better.  With SRPR each ladder is worth a maximum of 10,000 points.  With AF there is no actual maximum; the highest score is determined by the number of players on a ladder.

For SRPR the following procedure is followed:

  • Get the site record and divide it by the player's record to produce a SRPR value.
  • Add the SRPR values for each record and then divide by the number of records to produce an average SRPR.
  • Multiply ASRPR by a weight.
  • Do the same for lap (if present).
  • Add everything together.

For AF the following procedure is followed:

  • Get the rank for each record a player has on a ladder.
  • Add the ranks together and then divide by the number of records to produce an average finish.
  • Divide the number of players on the ladder by the player's AF to produce a value.
  • Take the LOG10 of that value and then multiply by 1000 to produce a score.

What are the weights?

The course and lap records are each worth 50% of the total score.

Why does 1st place in one ladder score differently than 1st place in another?

With SRPR each player's score is a ratio of their time to the MFO bests.  In order to have the same score in multiple games a player would have to have all the MFO bests in each of those games.  With AF in order to have the same score in multiple games each game would have to have the same number of players and the player would have to have the same AF in those games as well.

Why is Climax counted on the ladder?

The 2010 F-Zero Time Attack Championship is a basis for judging the best player across all F-Zero games.  The availability of those games is irrelevant.  Climax is much easier and cheaper to acquire than a 64DD, and any hard-core F-Zero fan shouldn't be without it.

Is it the system we had before?

No. On the previous time attack championship ladder Climax did not count, and GX snaking was not an option for GX score.  With the previous system the smallest score was considered the best score.  The old system used only totals, but in the new system every record counts.

Does not new system give same result, usually?

No.  The new system doesn't use ranks.  Both SRPR and AF will not produce the same values as the old ladder.
