It's like a disease

This is the chart I thought I was looking at in the first place. It plots the total amount of energy used as the number of uses increases. The number of uses along the bottom are in factors of 10. So it goes out to 1500 uses.

Somewhere around 700 uses, the foam cup starts to be more expensive than the ceramic.

I swear, I'm done with this.
