The example numbers I posted would give 10%.
The pricing was easy enough that the 10% worst case could easily be pulled from it.
I wouldn't trust the numbers from someone who needed a model to go over to see that and I seriously thought you were joking about not getting where the 10% worst case was from.

I don't think "arbitrarily" is the right word to use here. Your mental model might have been $0.99 as the pricing floor, but that mental model does not represent the reality of mobile app stores. Paid apps are a minority on both iOS and Android, the dominant revenue model for mobile games is to offer free downloads/installs with advertising and in-app purchases.
Your "mental model" didn't consider 80% of the market by revenue?
