Table 3. Deviance of session length data from theoretical models of daily session length fluctuations.

Model	Sample 1	Sample 2 direct replication	Sample 2 adjusting time zone
Limited SC	2.8*10^3	2.0*10^3	2.4*10^3
Unlimited SC	3.1*10^3	2.0*10^3	3.0*10^3
Evening preference	1.2^10^3	8.0*10^2	9.3*10^2

Notes: Values are the negative log likelihood of the data given the model. Smaller values imply Notes: SC = self-control. Values are the negative log likelihood of the data given the model. Smaller values imply less deviance and greater likelihood. See Fig 2 for representations of the theoretical models.
