Dear Liviu

i hope you add "Max gaps between a set activites" like "Min gaps between a set activites" in activites time constraints.

best regards

But why do you need such a constraint? It sounds weird, and I think it would confuse the normal users, that is why I am reluctant to add it. And it also seems difficult, I am not sure, because I do not understand exactly the requirement.

Based on what I have read on arabic section
I thinks a user needs a constraint like this:
Max gaps continuously
similar to:
Max hours continuously

It seems this user allows gaps for teachers in a day, but he wants to control how many continuous gaps
Some times FET gives hims 3  continuous gaps,
maybe he wants to put this down to 1 ot  2 continuous gaps

Maybe he could try a trick: say teacher T allows 4 gaps per week. Then, add 4 activities, teacher T, no students, any subject, activity tag "Gaps", each duration 1, no min days constraints between them (0 days in add activity dialog). Add constraint teacher(s) max 2 (or 1) hours continuously with activity tag Gaps.

The only problem: good situations in which the teacher T begins (or ends) his day with 3 consecutive gaps, and he has only 1 other gap in the week, are excluded, FET cannot accept them. But in practice he might find good solutions, maybe working progressively.

I think he should try using "max gaps per day" and "max gaps per week" at the same time.

(of course "max gaps per day" < "max gaps per week".)

sorry i don't see the replys.
but some teachers have 15 gaps in the week (hour or gap = 45 min), and fet can't add more than 10 activites per week for activites tag.

No problem, add an activity split into 10, then one split into 5 (no min n days between the 10 or the 5).
