I think the reason was that they added the later year, but yes, it was unfortunate.
I don't think the bus companies are as good value as NEBOA claim they are and I don't think they're as bad value as Nexus claimed.
The panel actually thought 8-10% was realistic, given the market is currently at around 13%. The issue was the 40% optimisation bias that they placed on Nexus, which had the immediate effect of making everything look unaffordable. The idea, put forward by NEBOA, that the existing network would collapse under Nexus control is laughable.
I agree, I highlighted the criticism. The panel did, however, decide to take all these promises at face value, adding them into the value calculation despite the behaviour of NEBOA.
If the promised improvements do actually arrive then I'd say it was a success of Nexus, in that NEBOA had no interest in providing any improvements until they realised Nexus were serious about the QCS. If Nexus hadn't gone down the QCS route I doubt we would have seen the investment, especially from Stagecoach and Arriva (Go, in fairness, were already improving rapidly under Huntley, although they were starting from a very low base).
I have a vested interest as I live in SE Northumberland and not in Tyne and Wear, but this is the main reason why I was against the QCS. There are many issues for people living where I do- the complete lack of integrated ticketing, for one thing- and I actually think a QCS would have made things worse. I live less than three miles from a Metro station yet cannot buy an integrated Metro and bus pass, and I think the QCS would only have made the situation worse.
As I've said, I don't think we need the rigidity of a QCS, and I think that rigidity would make some parts of the system worse. But the issue was that NEBOA have been completely unwilling to work with Nexus for many years and, certainly in the case of Arriva and Stagecoach, have been happy to massively underinvest in their network whilst creaming the profits off. The threat of a QCS made Stagecoach and Arriva pull their finger out; it'll be interesting to see if they retain that motivation now the threat of a QCS has gone.
