tl;dr @mray is actually right
We discussed 3 hours in mumble and found out where we talk past each other and where able to agree on things.
He is right that i can’t compare a 10 patron goal to a 100$ goal. I have just invented those numbers for my example.
To compare that, we would need real world numbers. In one case with a crowd-size goal and in another parallel reality the same patrons and a money goal. That is not possible. And projects are different. Popular projects have many patrons and niche projects could have enthusiastic patrons that pledge a lot of money. We could do A/B testing to get real world data.
So i simplified my example more to argue for my point. We have a money goal. Say there is someone that want to join the crowd and think how much they should contribute. They are on the project page on our platform and put in 5$ in the text field. They get direct feedback how that affect the rate (%). Now they put 10$ into the field and the bar moves more. They understand that 10$ has a higher impact than 5$.
Robert agreed that this effect exists. But in a realistic case, we have more patrons and a higher goal than in my simplified example and the difference is so small, that you don’t even see it. Less than 1%!
example
rate = total pledges / money goal x 100
rate = 25,000$ / 50,000$ x 100
rate = 50%
project get 12,500.00$
5$ pledge
rate = 25,005$ / 50,000$ x 100
rate = 50.01%
project get 12,505.0005
you pay 2.5005
your matching is 2.5$
10$ pledge
rate = 25,010$ / 50,000$ x 100
rate = 50.02%
project get 12510.002
you pay 5.002
your matching is 5$
100$ pledge
rate = 25,100$ / 50,000$ x 100
rate = 50.2%
project get 12600.20
you pay 50.2
your matching is 50$
500$ pledge
rate = 25,500$ / 50,000$ x 100
rate = 51%
project get 13005
you pay 255
your matching is 250$
it’s interesting that you pay always slightly more than your matching
Robert argues that you could show a similar number with a crowd-size goal, like: “your 1$ donation will result in X$ matching from the crowd”.
example
the project also want to get 50,000$ and know the average pledge is 5$
rate = number of patrons / crowd-size goal x 100
rate = 5,000 / 10,000 x 100
rate = 50%
project get 12,500
1$ pledge
rate = 5,001 / 10,000 x 100
rate = 50.01%
project get 12,503.0001 ((5000 x 5 + 1) x 0.5001)
you pay 0.5001
your matching is 2.5$
5$ pledge
rate = 5,001 / 10,000 x 100
rate = 50.01%
project get 12,505.0005 (5,001 x 5$ x 0.5001)
you pay 2.5005
your matching is 2.5$
500$ pledge
rate = 5,001 / 10,000 x 100
rate = 50.01%
project get 12,752.55 ((5000 x 5 + 500) x 0.5001)
you pay 250.05
your matching is 2.5$
it’s interesting that the matching is always 2.5$. your pledge has no effect
5$ pledge / 2000 patrons
rate = 2,001 / 10,000 x 100
rate = 20.01%
project get 2,002.0005 (2,001 x 5$ x 0.2001)
you pay 1.0005
your matching is 1$
5$ pledge / 4000 patrons
rate = 4,001 / 10,000 x 100
rate = 40.01%
project get 8,004.0005 (4,001 x 5$ x 0.4001)
you pay 2.0005
your matching is 2$
5$ pledge / 8000 patrons
rate = 8,001 / 10,000 x 100
rate = 80.01%
project get 32,008.0005 (8,001 x 5$ x 0.8001)
you pay 4.0005
your matching is 4$
5$ pledge / 9999 patrons
rate = 10,000 / 10,000 x 100
rate = 100%
project get 50000 (10000 x 5$ x 1)
you pay 5
your matching is 5$
Robert also said, that i get less matching when i pledge more with a money goal. I guess that’s correct, but i haven’t calculated it.
At the end, i said that i’m happy that we can still talk friendly with each other, even tho we disagree a lot in the forum. At times it can feel like we fight each other, but in the end we work on the same goal and know we have the same values. I’m happy with this result. Thanks for your time!
Before thinking further about this approach, i will check out the new proposals.
