Yes, they are sometimes balancing load, say where there are 3 nodes on one card and a single node on another they will move a node to another card. This is an upgrade to the 3 nodes, all of them have more bandwidth per modem post-resegmentation.
The resegmentation programme is ongoing throughout that 'general area'.

That contention ratio seems reasonable but it is a very small fragile amount of shared bandwidth, evident by the downstream congestion on the legacy network.

Due to the relatively small customer population it generally works fine. Most of the 20Mb customers will be on the overlay network.
There's relatively little downstream congestion on the legacy network, it's largely overlay network upstream congestion that's the current bugbear.
Incidentally 300 x 10Mbit customers on 38Mbit is about 80:1 contention ratio
