Actually, it's X per patron, not "other patron" The math is this simple: You pledge $1 per 1,000 patrons, so that means if there's 340 patrons, you donate $0.34. If there's 3,400 patrons, you donate $3.40. There's no formula to explain. It's that simple. We used to have a more complex formula for certain objectives, but the complexity was too cumbersome. There's nothing exponential here. The quadratic thing is simply this: 1,000 patrons * $1 = $1,000 but 5,000 patrons * $5 = $25,000. Basically, it's quadratic because it's linear increase in patrons * linear increase in per-patron donations. So the *total* is quadratic, but each patron's donation increases linearly. The key items are: "you pledge X per patron", "your pledge today will be X * Y given Y patrons", "your matching from others will be Z", the total from everyone is A" >> On Sun, Oct 18, 2015 at 9:56 AM, Jonathan Roberts >> <robertsthebr...@gmail.com <mailto:robertsthebr...@gmail.com>> wrote: >> >> The math is unclear to me as well.
