First time seeing this analysis. It all makes sense once I understood that you were trying to determine whether DEC was net burned or printed.
If you wanted to get more accurate, you could look up each recipient of a mystery reward and find the most recent mystery potion transaction to get their exact cost.
Thanks for the feedback. An explanation of analysis purpose is definitely needed.
This would be interesting to do but I'm not sure the feasibility of tracking all those transactions. An idea to consider later on though 👌
