Your 96.8% sounds like the BT Wholesale IP Profile of 96.79% on non-G.INP, and your 76Mbps the Ofcom imposed figure for the sync 10% of customers can achieve. Neither of which refer to throughput.
Throughput may be being quoted from speed tests, many run wirelessly connected to the router.
We often see speed tests on these forums above 74mbps, but 76Mbps?
