Frankly I don't understand what the problem is with these tickets. I think you are barking up the wrong tree entirely by worrying about their relationship with the schedule.Actually, that's not the hint.
The hint is that those designing the timetable may not be taking this cohort into account much or at all, because either the data on them is poor, or because no-one is incentivised to take them into account, or both.
Lest there be any misunderstanding, the suggestion is not that this should be a 'major' consideration on its own, any more than students compelled to reach Newcastle College by 9am should define the timetable, but they both exist and it's relevant to consider all stakeholders.
My suggestion would be if you disagree it'd be a good idea to create a dedicated thread setting out your point about them, as it's going a little away from the topic here.
