I've just read the Guvmin's supposed justification for their tiering system.

As everyone suspects, it provides absolutely no detail on why they took a broad area approach to tiering rather than assessing individual boroughs within Counties. That's absolutely not there.

In other words, the tiering system is either for administrative convenience or just a pretence at reasonable tiering.

It's a rubbish document because it tells us only what we've been told before.
