Wow, I almost fell out of my chair when I read this. 96% of CM participants are merits sources ?? I'll have to check that.
So of the 55 participants of the CM campaign, 28 (5 of which are Staff members) are indeed merits sources.
Of the 25 participants in the Bestchange campaign, 6 are merits sources.
You can deduce what you want from these numbers, but you have to take into consideration that the CM campaign is 137 weeks longer than the Bestchange campaign. Probably a small insignificant detail.
I think this is just a coincidence, since DS_ selects users in such a way as to make the most extensive and high-quality advertising coverage, including local sections. And of course, users who are active in the appropriate sections and who were accepted into the campaign sooner or later think about becoming a m'source
(well, or submitting an application). Moreover, I would not include the forum staff in this statistician, since they have become the default m'sources.
