I take Igni on at my peril - so I won't, this time.
You presumably mean that the CMTS has been upgraded to support 16 or more downstream channels and 8 or more upstream channels. You then ask how much increase in speed would you see in an over utilised segment.
Igni's answer is correct. To answer that question the way you would have liked needs more assumptions which can't really be provided. This notional "over utilised segment" concept needs to be bounded by the number of connected homes, their concurrency, segment and node details before/after any re-segmentation (if any).
You can say that if, without re-segmentation, they add downstream capacity such that the additional downstream channels are not pinched from an existing set, then at the instant of cut over to the new system, downstream congestion would be halved.
HTH and I await some scathing point of disagreement from Igni.
