Having checked, there really are over 15000 bets pending settlement, but most of them are below the minimum bet. I didn't used to count those, but recently accidentally started counting them.

I'll re-ran the script and had it ignore bets under the minimum, and:

"Total of 35 bets unaccounted for."

So that 15k number was including rejected bets. Oops!

Here's an updated report with data from the most recent blocks:

Quote

Total of 50 bets unaccounted for.
