99.99% consistently, and that might actually be understating it. Anything that is missing the brackets can be considered a signage error (I can only think of one instance) and not worth constructing an entire data model around. Dave and Derick are right in that any one road in the UK can only have one ref, other than the unsignposted European E routes of course. More fundamentally, these are "route relations". Road numbers in the UK, unlike the US, do not represent "routes". They are just road numbers. There are plenty of numbers in the UK where no-one would use that route to drive from one end to another, or even to a halfway point, following the number all the way. In many cases, such as the A47 between Birmingham and Leicester, the concept of a route has long been lost. Historically there is a designated route concept in the UK in the sense that some countries have them, but it doesn't map to road numbers, has largely fallen from use, and is neither signposted nor verifiable: http://www.watsonlv.net/pdf/trunk_roads.pdf These route relations are pointless armchairing and make the map harder to edit for newbies to no benefit. If the user doesn't respond to changeset comments I would agree with deleting them.
