How realistic must simulated failures be? Low fidelity suffices with little data

From the JHU robot RL paper thread (5/n): how realistic does a simulated failure need to look?

Analyzing visual fidelity at different data scales: with little data, low-fidelity simulation can match high-fidelity simulation; as data grows, the higher-fidelity version holds up better.

A practical cost hint for teams using real-to-sim failure data to train reward models: maximum fidelity isn't necessary on a tight budget.
