GuildRanks

This does not include normal/heroic bosses or reclears of mythic bosses, only pulls up until the guild kills the boss on mythic for the first time

This does not include normal/heroic bosses or reclears of mythic bosses
This is a measure of the amount of time from the start of the first progression pull during a raid period until the end of the last pull, breaks included
If there is a gap of more than 1 hour between pulls then that is not counted and it is assumed the next pull is the start of a new raid

This is determined by the amount of tier items equipped in the final mythic boss kill during the first reset
Even if only doing 2x 20 man splits there is a significant difference in the amount of tier sets you can complete during that first week
Which was a large advantage especially on Rashok which was close to impossible week 1 without splits
With the data available in the competition logs it's not feasible to automatically determine if a guild ran 2 split groups or 12
But even 2 splits are still splits and a huge advantage for the metrics on this site
The number is the amount of tier set bonuses (2 set counts as 1 and 4 set counts as 2) that were active in the final kill of week 1
