I already have reported it to them, but they will not take it further unless the all knowing BT speed test shows it. I finally got it showing reduced speeds on one test
That doesn't sound like the same problem then. The issue from last year only affected single-threaded tests and the BT test is multi-threaded. I don't think it ever gave me bad results. It was only ever TBB's test that showed an issue or file downloads.
Depending what the BT test is trying to prove that may or may not be wrong. If its purpose is to determine your maximum line speed then the test is correct. However if it's trying to determine network throughput it's a grey area. Knowing how BT manage their VLANs I'd be inclined to say it's still correct.
What I take issue with therefore is ISPs that insist on using the BT tester as proof of a fault. To my mind that is not a valid use of the tool as it can mask issues that lie within the ISP's network.
