Did most cryopreserved humans go 24 hours before cryopreservation?

Question

In my LessWrong essay "Nectome: All That I Know", I make the claim: "Most cryonics clients wait over a day between legal death and being cryopreserved." This is hard to check, but might be possible to verify at some point in the future. This market will resolve YES if there is strong evidence that a majority of people who were cryopreserved before 2026 spent at least 24 hours after legal death but before having their remains vitrified at cryogenic temperatures. It will resolve NO if there is strong evidence that a majority were cryopreserved with less than a day's wait time. I won't resolve until there is clear, unambiguous evidence about how it should resolve. I also won't bet.
