Help tighten up a calculator for cost effectiveness of addiction treatment?

Hi, community! I'm working on a calculator to show cost of DALY Averted and Cost of Lives Saved for different substance use disorders when they are treated with GLP-1s. I'd love to collaborate with folks who have built this kind of calculator before, and can help me create a rigorous case for potential funding (if the calculations indicate it's worthy).

I have a draft built in Google Sheets, and while I hesitate to share it publicly until I know it's solid, I'd be glad to share with anyone interested in strengthening it with me.

edit: please feel free to DM me if you're game to help.
