How much can one safely cut this cable back by? It would be a useful measurement to note down.
I feel I ought to be better informed in case I ever get round to trimming back the over large cable VM installed my box with. Well, I thought it was over long at the time but he had it already made up in stock in the van so he used it. Now I'm starting to think it might actually be the minimum length cable that the system can tollerate, and that it only seems long because my Shub is right next to the terminal.

Signal power level varies with cable length. Altering the cable length will alter the power level at the modem or set top box. This isn't a problem unless the power level is already on the edge of tolerance (whether too high or too low) in which case you get problems.
Network techs deal with power level issues by fitting an attenuator to reduce power or by moving the cable to a higher tap in the street cabinet to increase power. But if they are called out to a power level issue caused by a customer messing with his own wires, the customer gets charged for the call-out.
