Your numbers are very similar to mine. The exception being that I have a HIC connected as well (used in reverse) and my Joey is on WiFi. I'd say they're pretty normal numbers so it seems for two Duo Nodes hooked together. Your setup should have green MoCA bars on all receivers, unless there's some software glitch. One of my Hoppers had red bars once but the numbers were way lower than usual. A reboot fixed it. Had to have been a software glitch.
Another anomaly is that since adding the HIC the two Hoppers that aren't on the same node as the HIC show yellow bars. Based on the counters the HIC is a lot weaker device than the Hoppers/Joeys. While all of the receivers have bit rates in the 280s-290s the HIC is only 250 or so on the Hopper that shares a tap with the HIC, as well as the other Hopper on the same Duo Node. The HIC is only in the 170s on the Hoppers that are on the other Duo Node, which probably explains the yellow bars. I only use the HIC to connect a NAS across the house to the router, using the bridged Hopper on the same Duo Node, so I suppose the bit rates on the other two Hoppers don't really matter. Even at that though, 170 Mbps is still more than the HIC/Hoppers' 100Mbps Ethernet ports are capable of anyway.
Another thing I noticed is that having two Duo Nodes tied together slightly lowered the bit rates in comparison to a Duo Node and a Single Node tied together. I might swap CLIENT ports on the jumper cable just to see if that has any effect. I'm not really worried about it though since everything works great and the bit rates are still good.
