Interesting numbers there...
As the 8800NL seems to follow the usual Broadcom behaviour (of overestimating attainable speed when interleaved), we'd expect an "open profile" speed of around 72Mbps. So that's an extra 4Mbps from G.INP.
It's good to see that DLM might be back to a 2-day time to switch from a reset-induced interleaved profile into a G.INP profile. A real shame a line like this needs manual intervention to unstick the banding. A worse shame that the humans can't trust that DLM is getting a decent balance.
G.INP retransmission looks to be working at least twice as hard as on the banded line, judging by the Retransmit-TX, Retransmit-Corr and LEFTRS graphs. But working pretty much successfully, with only 1 ES.
