(This came up because the idea was included in an illustration idea at Suggestions for How it works )
For reference, the concept of more-and-more matching of each extra cent is something we presented early on at https://wiki.snowdrift.coop/about/mechanism#existing-patrons-match-each-new-patron — so the chart there is just another way to see the same pattern.
The math isn’t that far off, but the presentation is confusing. 10,000 people each giving a penny is $100. So, when the pledge value goes up by 1¢, the 10,000 patrons together give an extra $100.
Of course, in our crowdmatching, the only way to raise the pledge value by 1¢ is to get 10 new patrons. So, we actually get ~$200 extra because of the increase in pledge value and patron numbers.
- Each of 9,990 patrons gives $9.99, project gets $99,800.10
- Each of 10,000 patrons, gives $10, project gets, $100,000.
- Each of 10,010 patrons, gives $10.01, project gets $100,200.10
Around 10,000 patrons, each penny more than I gave before is part of the project getting ~$200 extra (~$100 extra from the existing patrons plus ~$100 extra from 10 new patrons each giving ~$10).
Whether this framing is especially convincing or important, I’m not sure. But maybe this framing or variations of it could be tried to see how it connects with people.
