Guild Tracking

How are 25-man and 10-man raiding separated?

Wowtrack counts the number of guild members that earn a criterion or achievement on a specific point in time. In assigning first kills to brackets it follows the in-game definition of a guild group with adjustements for optimized tracking.

In addition, Wowtrack also considers the number of loot items obtained by guild members per kill. This is especially important for the ranking of guilds that formed or changed bracket during progression. Note that for a loot item to be considered, the disenchant roll option must not be used. Manual disenchants are fine.

Guilds are assigned to the 25-man or 10-man bracket based on the majority of their kills. Heroic difficulty kills are counted independent of normal difficulty kills, and the heroic difficulty bracket overrides the normal difficulty bracket.

How are points assigned?

Points are assigned as follows:

Encounter Type Points
Normal 1
Normal End Boss 2
Heroic 2
Heroic End Boss 4
Special 8

Points decay with each calendar day following the release of a patch. After 360 days, points are halfed. More formally: points(d) = points / (1 + d / 360), where d is number of calendar days since the release of a patch.

How is the ranking calculated?

The ranking is calculated based on the point sum of each guild. For normal difficulty encounters, points are considered regardless of the bracket in which they are earned. For heroic difficulty encounters, points are considered only if they match the guild bracket. This distinction is due to the way both the armory and the flexible raid lockout system work on normal difficulty.

For normal difficulty encounters, the first kill is considered regardless of bracket. For heroic encounters, kills matching the guild bracket override non-matching kills. This allows a 25-man guild to defeat an encounter with a 10-man (alt) raid, and still receive points in the 25-man guild bracket once the encounter is defeated in that bracket.

Once a guild finishes a patch by defeating all encounters, the ranking is based on the time the final encounter is defeated.

Why are some 25-man normal difficulty kills detected as 10-man kills?

This may happen due to the way the armory and achievement system work. This issue applies to normal difficulty encounters only and has no effect on the ranking as points from normal difficulty kills are considered regardless of the bracket in which they are earned.

Are the ranking rules fixed?

Wowtrack strives to provide a high-quality ranking that is accepted by the community. Therefore, the ranking rules can be modified if a change is consistent with that goal. Changes are typically communicated on our blog and Twitter account.

Character Tracking

Can I disable the character page of my characters?

The character page contains statistics and information about a character, such as its name, its patch history and its guild history. If as the player of a character you prefer that this information is not displayed by Wowtrack, you can disable the character page. In order to disable the character page for a character, you must first claim the character by visiting the character page, clicking Claim and following the instructions. After the character has been claimed, the character page can be disabled in your Profile. Disabling the character page also disables character news and favorites for that character. Due to caching technology, it may take up to 24 hours until the enabling or disabling of a character page takes effect. Also note that Wowtrack may have multiple entries for a character.

How are encounters and points calculated for characters?

Essentially, encounters and points are calculated in the same way as for guilds. In difference to guilds, encounters and points are only calculated for characters if content is completed while it is current, i.e. before the next raid tier is released.

How are challenge modes calculated for characters?

Each challenge mode rewards points based on the bronze and gold times. Completing a challenge mode exactly at bronze time rewards 0.0 points, and any faster completion rewards linearly more points up to 1.0 points for a completion exactly at gold time. From there, any faster completion rewards linearly more points up to 2.0 points for a theoretical completion in zero time. The points shown per patch correspond to the sum over all challenge modes completed by the character.

Encounter Tracking

How is the relative encounter difficulty calculated?

In a nutshell, it is calculated by comparing the success ratio of 25-man and 10-man raids per encounter to the same ratio calculated over all encounters. More formally, the relative difficulty is calculated as follows for all encounters e with at least one kill on both raid sizes:

  1. Ratio2510 = GeometricMean(25ManKills(e) / 10ManKills(e))
  2. NumGuilds25 = max(Num25ManGuilds, max(25ManKills(e))
  3. NumGuilds10 = max(Num10ManGuilds, max(10ManKills(e))
  4. ExpectedKills25(e) = min(10ManKills(e) * Ratio2510, NumGuilds25)
  5. ExpectedKills10(e) = min(25ManKills(e) / Ratio2510, NumGuilds10)
  6. RelativeDifficulty25(e) = (ExpectedKills25(e) - EffectiveKills25(e)) / ExpectedKills25(e)
  7. RelativeDifficulty10(e) = (ExpectedKills10(e) - EffectiveKills10(e)) / ExpectedKills10(e)

Step (1) determines the average ratio of 25-man kills to 10-man kills as a geometric mean over all encounters. Steps (2) and (3) approximate the number of guilds that are capable of killing an encounter in a given raid size. This is either the number of guilds in the respective bracket or the maximum number of guilds that have defeated any encounter, whichever is larger.

Steps (4) and (5) determine the expected number of kills given the number of kills in the other bracket. This is calculated using the ratio from step (1) but limited by the number of guilds calculated in steps (2) and (3) respectively.

Steps (6) and (7) calculate the relative difficulty as the difference between the expected and effective number of kills normalized by the expected number of kills. The relative difficulty is a value between -inf and 1, where 0 indicates equal difficulty and 1 indiciates maximum increased relative difficulty. The relative difficulty is only shown for non-negative values, as a negative value would indicate easiness rather than difficulty.

Please note that these steps are carried out independently for normal and heroic difficulty encounters.

As the name implies, the relative encounter difficulty is an indication of relative difficulty. It is not an indication of absolute difficulty. Calculating the absolute encounter difficulty would require factoring out player skill.

Patch Tracking

Can you elaborate on the percentile statistics shown for patches?

Sure. Please see this blog post.
