To help understand the true scarcity of uninterrupted time, the RescueTime data scientists also calculated the longest interval that each user worked with no inbox checks or instant messaging. For half the users studied, this longest uninterrupted interval was no more than forty minutes, with the most common length clocking in at a meager twenty minutes. More than two thirds of the users never experienced an hour or more of uninterrupted time during the period studied.
