Nir I politely disagree.

I think progress by task is more important than working a specific amount of time under the tyranny of a daily routine.

I think you and Damon Zahariades (author of the todo list formula) should have a debate and meet in the middle.

Lookup my article that was inspired by his book:

Also check the article from Ash Jurberg on his 168 hours work cycle where he gives important insights on many points related to time and todo list issues:
