It entirely depends on which tasks you have and where they are coming from. Not every task has to some unique hour-long work. People who are using routines, pre-defined lists or elaborated project-planning, usually have very detailed and long daily lists full of small tasks, each in the range of some second to minutes of work.

Maybe the 133 items are 120 items of one minute work each, and the rest are conditional or optional task you will not do that day.
