@L.M.Sherlock I’ve figure out what’s been bothering me about the structure of your simulation, and it’s a pretty simple fix. These graphs triggered it:
You’re stopping the simulation way too early. It seems like, and correct me if I’m wrong, you’re stopping the sim as soon as all new cards have been introduced. At that point there’s still a huge backlog for most of the sorts and you don’t really know all the cards that well.
What should probably be done is you simulate until all the cards’ R value is above the DR, which is going to be much later than all the new cards getting introduced. Then, we can see how much total time it takes to get there.
I know you’re going on vacation so I’ll try to do it myself in the meantime.
