consistent among customer base I meant.

its defenitly not a consistent good performance across all of VM's areas, far from it.

sky LLU customers for the most part only have varying speeds due to line sync speeds, when they have FTTC it will blow VM out of the water.

Me too. The TBB speed tester isn't reliable for the 50 meg service. Maybe not for cable as a whole but maybe that's going too far as I haven't researched the totality I'm implying.
