How does this site fairly track a member's contribution?
Three things, all pulled straight from the game and hard to fake: donations (troops given to clanmates), war attacks (stars earned in regular wars and Clan War League, adjusted for how much harder or easier the target was), and raid attacks (Capital Raid Weekend attacks used). These are the three things almost every active member does regularly, they're visible to the whole clan in-game, and none of them can really be gamed — an attack either landed stars or it didn't, a donation either happened or it didn't.
Why doesn't this track Clan Games, Season Pass, or other events?
Mainly because the Clash of Clans API simply doesn't expose that data — there's no endpoint for a member's Clan Games points or event participation, so there's nothing to pull. But even if there were, donations, war attacks, and raid attacks already cover the three things that matter most to a clan week in and week out, so this site keeps its focus there rather than chasing every possible stat.
How is MR (Member Rating) calculated?
MR is one score built from three things, added together:
- 1 MR per troop donated.
- 25 MR per raid attack used this month (stacks across every Capital Raid Weekend in the calendar month).
- 50 MR per war star this month, from both regular wars and Clan War League — adjusted by how much harder or easier the target's town hall was: half value (25 MR) against a target 2+ town halls lower, up to 1.5x (75 MR) against a target 2+ town halls higher. Map position is ignored on purpose, since war matchmaking can assign unfair map numbers — only the actual town hall gap counts.
