You mean per stop/route pair? That's an incredible s amount of relations!
It seems to me that it would be a nighmare to try and maintain it that way.
At first sight it seems simpler, but with the new proposal i came up with,
you can see how the stops of a variation in itinerary tie together.

If the vehicle remains in the station longer, the roles could become
00:30-00:35 instead of simply 00:35 for the departure offset to the time
the vehicle left at its first stop.

Seeing the stops in the timetable relation in the order they are served
also enables comparing this with the stops sequence in the route relation
they refer to, adding additional possibilities for validation of the data.

The stops in a timetable sequence should always be a subset of the stops in
a route relation and appear in the same order.
