Nice, I didn’t know OpenPhil had calibration training.
It is difficult to use SPIES for the calibration training—I kept running out of time when using my implementation in Python.

Here are the results; I’ve only included 5 questions, but from what I’ve done, it seems SPIES helps me to narrow might 80% confidence intervals.
1. In which year was the US Open decided for the first time by ‘sudden death’?
