I'm sorry to say that you don't seem to have a clue about how data communications work, and it would take rather a long time to explain.
You initial enquiry was very odd, given what you said in your OP:-
I've been in networking and computer fields for nearly 30 years. I admit I don't know everything, but I'd like to think I've heard near everything. I've never heard this before.
Your reply to me suggests you didn't understand my previous reply either. I was trying to explain that the reported/observed connection speed on wifi from a router does appear dynamic. Unlike the connection speed on physical connections.
However, that reported wireless speed varies depending on the fluctuating electromagnetic conditions within and around the premises. Including other local wifi routers' activities.
The only explanation I can think of for your confusion is that you are accustomed to an environment where the connection between the modem on the premises and the one in the MSAN/DSLAM providing the service is using SRA. (Seamless Rate Adaptation)
. This is not in common use in the UK for broadband connections. Variable noise margins are generally used and automatic re-syncs between the two modems occur only if the noise affecting the line increases enough to exceed that margin.
If you were to re-sync your modem you would probably end up with a different speed. If you provide the basic line stats, current speed, max available, noise margin or SNR or SNRM depending how your equipment labels it, and attenuation, we may be able to help advise whether the new speed would be higher or lower than your current 53.54 Mbps.

Connection - Three 4G, tbb tests normally 35-45Mpbs down, 65Mbps off-peak, 9-24 up.
