Super hub 1 vs hub 5 latency

So the words be careful what you wish for comes to mind but I would of needed to roll over with a hub 5 at some point in any case still happy.

This was my super hub 1 BQM

This is my hub 5 BQM

Does it course any problems in gaming you might ask? No mainly as long as the minimum and maximum are not that far apart there be no problem. That said more average jitter on the hub 5 which my super hub 1 some times does but unsure why and its not caused by uploading or downloading at the time but that does cause it to happen but not in this case.

Super hub 1 average change

Also a 3ms~ RTT to 192.168.100.1 on hub 5 vs 1ms on super hub 1 hmm odd which seems to add to the minimum latency in BQM on the upstream which might be due to the hub 5 QoS/BWM when rate limiting.

The question is does this thick blue average a setting on the hubs or Docsis upstream method to cause it? And is it better to look worse then look better to be worse?

    Could it also have something to do with the SH1 using way less channels than the H5?

    So I think I have worked out why the latency is different on super hub 1 you can have low idle upstream bandwidth and not show what it shows like on the hub 5 but the hub 5 at a really low idle bandwidth no problem but some idle bandwidth and its not much like 0.3Mb causes the hub 5 to do some low random delaying of packets in groups not by much like 3ms before it gets to the docsis upstream buffer at the modem to then send which is why my BQM looks jittery then it was with super hub 1.
