The Roblox proposal on Area51 has a component commitment score of 42% (though an overall commit score of only 5%, owing to having only 5 committed followers who have scored more than 200 on SE sites other than Area51). Click on the "more info" at the bottom of the blue panel in the top-right corner to see the commitment component scores.

The calculation of the component commitment score is apparently:

UserScore = SUM(Reputation >= 200 ? 0.233 * ln(Reputation-101) - 0.75 : 0) + 1.5

How can those 5 users have amassed enough commitment points to bring the Roblox component commitment score to 42%?


The formula applies to all committers, not just the 5 with reputation over 200. Further, the SUM represents the sum of scores for each of the sites a committer with 200+ rep participates on. So, all committers except five would contribute "1.5" to the commitment score and the rest would have a variable contribution depending on their rep across the sites they participate on.

I haven't run the numbers, but it seems plausible that you'd arrive at 42% after considering all of the committers to the proposal. (There's also the commitment decay to account for, but that'd bring the number down, if anything.)

    Assuming the stated formula is correct, only 5 users (the 5 with scores equal to or greater than 200 on any site) would have a non- constant "UserScore" ((Reputation >= 200 ? <calc> : 0) + 1.5). The sheer number of committers could account for the relatively high commitment score. – user149432 Mar 14 '12 at 20:29
  • @MarkTrapp Yeah, you're right - only the 200+ five would have contributed something other than 1.5 to the score. I'll make that clearer in the answer. – Adam Lear Mar 14 '12 at 20:49
