Both models’ loads came out 84-100% clean, so is the score mostly just how much they fit?

Totally the opposite, there's a detailed dishwasher simulation under the hood: ray tracing, splash simulation, soak, heat, enzyme action

I calibrated it against my actual dishwasher by doing some test runs with baked egg

As we know from physics, even the most sophisticated mechanisms (e.g. friction) often ends up having a very simple model (proportional to the normal force).

Sooo, the score is maybe mostly just how much they fit?

Question for both: do you think that is also the case with a real-world dishwasher (it's mostly about getting stuff to fit), or do you think it's an issue with the current sim?

The sim needs work, for sure
