There is no need to make such groups within the table.
I don't think such change was requested in the previous reviews.
Also grouping the IDs the way you did is a bad idea.
1) Since the clocks are registered in the order of the table, this will
make a lot of orphans during the registration of the controller. It does
work but it is not ideal performance wise. Whenever possible, it is
better to register the clocks from the roots to the leafs.
2) These 2 nice groups are going away the minute you add another clock which
was not part of the original submission. This is why IDs have no meaning,
no even groups.
