This market resolves YES if, within a week following the publication of the verdict of the debate (tbd but expected early December), the probability of the main market changes by 10 or more percentage points either up or down and, for at least one continuous 24-hour period, it stays at, above, or below the new probability. 

If, before publication, the probability is 73%, this market resolves YES if, within a week (= 7 x 24 hours) after publication, there is a continuous 24-hour period when the probability is at least 83% or at most 63% (not counting transient spikes).
