So, at the very least you were wrong in saying that 'it is naive to expect a performance increase when upgrading to a new specification.'
I totally agree and it's a shame he missed that.

No he didn't "miss" that. You should not inherently EXPECT those increases based solely on changing from docsis 2 to docsis 3. If you get an increase, like you did, then great. But those expectations are what Jack is saying are naive.
As an example; it's the same lines of thinking that changing your lan environment from 100Mbit to Gigabit, and expecting the internet to be faster. Maybe in some cases people saw an increase in speed. But it's likely because they solved an underlying issue that they didn't realise they had, like a duplex mismatch. Expecting the internet to be faster is naive.
The same can be said for expecting an increase in speeds going from Docsis 2(Geo Metro) to Docsis 3(Dodge Viper) for the same service level(Speed Limit 35mph).
In your case you may have solved a hardware or layer 1 issue by replacing the modem.
