Constraint for max hours daily with an activity tag for teacher(s)

[infoo_]

Hello

In school there is a rule that says no teacher must teach more than 4 hours daily in a course.

In FET I created one activity tag for each course. 1A tag is for course 1A, etc.

I would like to know if using 'Max hours daily with an activity tag for all teachers' constraint applied for tags 1A, ... is less performant than using 'Max hours daily with an activity tag for a teacher' constraint applied only to teachers that exceed 4 hours daily.

Thank you!

Forget it.

I realized in some courses this rule does not apply. So it is impossible to generalize.

I think that additional redundant constraints might slow the generation, but only a bit.
