Resolves based on the initial release (i.e. subsequent revisions don't affect resolution). Resolves to the reported number rounded to the nearest tenth of a percent. [edit: this is under consideration— see comments — planning to decide by May 5]
Reported on May 15 (question closes just before release).

I’m just realizing that I have to resolve to a bin, not a specific number as I described in the description. And the bins are continuous, ie 0.4 is the end of one bin and start of another. Given that, I am leaning towards resolving both bins that include the rounded number. Let me know if you have any alternative proposals or feel that’s unfair.
(Since I was explicit about resolving based on rounded number, it seems worse to go back on that and resolve based on a number with more decimals.)
@Tyler31 i'd resolve it to the nearest hundreth of a percent, and if it's in margin (i.e. rounds to exactly 0.40) then resolve 50/50 (or to both buckets if you can't solve to a percentage)
