So I have a new router, ASUS DSL-AC88U (Broadcom chipset), which has G.INP support (which the HH5A does not) and IPv6 support (which the HH5A does not, it seems, although IPv6 seems to be broken on the BT side - separate post about that here).
Since installing it I have noticed that the MAX down rate is significantly higher than the old HH5A was reporting, and the SNR has jumped from around 5dB on the HH5A to 9dB on this device. It also shows that interleaving etc. is enabled on the line.
The device has been in place for about 3 weeks and has been very stable so I was hoping the DLM would "notice" the improved SNR and max rate thanks to G.INP and gradually increase the sync speed nearer to the max. Here are the stats

Can I expect the DLM to aim for a 3dB SNR target and gradually raise my sync speed?
I am about 200m from the cabinet and the audio quality on the line is crystal clear. BT NTE is fitted, with inbuilt filter and iPlate.
