It's all fairly clear now, to me at least.

3 channels x 11 dBmv hits the DOCSIS 3 limit.

4 channels x 8.25 dBmv also hits the limit.

I've noticed that some VMNG 300's don't like > 78 dBmv, others 8 dBmV. El cheapo modem is my take on that.

Masque mauy well be grateful that his team's observations can be rationalised to the DOCSIS 3 spec.
