Global dials
Adoption is the share of each opportunity actually implemented and captured. Every opportunity is linear in adoption, so one dial moves the whole set.
Adoption assumption
The opportunities
Each one is effect times volume times adoption. Ranges include the sustainer bonus, which credits the share of new gifts that go on to start a plan; the figure before the bonus sits under each number. Every card carries its pilot design.
The combined program
The same supporter is reached by more than one opportunity, so the gross is discounted. The discount widens as adoption rises, because the audiences collide more.
