Closer! Without the psychology and even when comparing 10% of annual income vs 10% of net worth at death, in a population of 750k givers that represent a normal distribution of ages and normal death rates, giving 10% net worth at death produces more donated dollars per year (even in year 1) versus giving 10% of income.
It’s still a psychology question! The people who die in year 1 and make up those increased donations haven’t had time to accrue interest, so they’re donating money you claim they’d never have donated if they were only 10% per year pledgers, which is a claim about donor psychology, and an unrealistic one at that!

I think most people are saving investing for life so I think I’m looking at it in more of a real world population than in a vacuum
