Hey Shaun,
I'd recommend pulling that data from the device normally facing their
internet connection. Does it support netflow or even just basic snmp
statistics that you could graph? Ostensibly the traffic level would be the
same regardless of whether using an LTE backup connection or the primary
internet connection unless you somehow prohibited certain traffic when on
LTE. Ultimately though, your best bet is going to be to get real stats over
the course of a couple of weeks and then you'll understand better the
traffic patterns based on time of day, day of the week, etc, as well, as
this is likely relevant.

Good luck!
