Ah the FTTC figures.
It should be noted they include non-OTT VoD, which the VM DOCSIS 3 broadband figures don't, include some broadcast TV delivered over multicast, which the VM figures don't, and include a bunch of extra data courtesy of Sky's pre-loading of STBs overnight with the most popular VoD products
The VM figure I mentioned is nigh on a year old, too. Probably somewhat different now and, of course, their figures should be considered against an FTTC and ADSL base, or middle and above tiers on VM only. All the people on VM's lowest tier because they hardly use their broadband will reduce the average considerably, as would all the people still on ADSL because they don't use the Internets much.
BTWholesale put peak usage per subscriber across their userbase at <500kb/s earlier this year. VM's was twice that at last inspection.
Lies, damned lies, etc.
