It appears the monthly number hasn't been below 0.4% since August 2021 (and event hat was just a dip). Any reason that number was chosen as the cutoff?
wasabipesto made M$23!

This was a mistake. I accidentally used last month's numbers. In retrospect, the question (which I shamelessly copied from Polymarket) was poorly worded and conflicts with the resolution criterion in the description.

Lol this market was improperly resolved. Actual number was .33%.

I think it's more likely than not.
