I understand having areas of "comfort" in the darkroom - even ones that aren't especially rational. I expect that there was once a logical reason for cliveh approaching things this way, and it somehow has become a habit.
This is really no different then some of the routines I use to help ensure consistency. The value is in the fact that they have become a routine, rather than the specific segments of the routine.
As long as cliveh isn't telling other people that they should/must approach things the same way, this is fine.
