Brier scores have stayed the same despite many forecasts' resolving

[patbl]

I created an account and imported my Prediction Book history. I think that since then, the Brier scores displayed by this UI element have stayed the same:

My memory is that 0.36 was displayed for "Last three months" even when I initially hadn't made any predictions yet (and all my Prediction Book predictions had resolved more than three months ago).

Hi @patbl - I think this was caused by the "last 3 months" looking at when PredictionBook questions were imported, not when they were actually resolved on PredictionBook. I've pushed a fix for this now in this commit.

I think this would cause your "Last 3 months" Brier to stay static if you have lots of "All time" resolved predictions, because a few new predictions won't change it very much. Could you see if it's now fixed?

Would you expect your change to affect predictions that had previously been imported from Prediction Book, or just new imports?

The past-three-months and all-time scores now differ a little bit, but that could be because I've been making and resolving a lot of predictions recently:

My date chart still goes back only to August—is this expected to be the case after your fix?
