Yes, I've also been unsure about what to do here.

The reason why I put them there is that, when looking at the code, it
is important to be able to quickly get the idea of where sched_data
points, at any given time. Therefore, being a little bit more verbose
than necessary would be, in this case, actually helpful.

Anyway, this is not a super strong opinion, so I can be talked into
getting rid of them, if others think we better don't have them too.

Thanks and Regards,
Dario
