There's a tolerance of 2 percentage points. So if there's a point in time where the market varied between 50.1% and 51.9%, that still counts as an uninturrupted stretch. (And I'd resolve to the midpoint of 51%.)

To be clear, this is about the longest uninterrupted stretch at a certain percentage, not the total added up over the whole lifetime of the market.
