Yes, I just have that problem filed as UK 5c from whatever guidebooks I've owned.

The other examples are of grades where the start seems to have been completely ignored in the tech grade (or at Shipley, the grade has been adjusted down for the crag being small, or for whatever reason).
> Wings was never given 6b for the top move was it?
Dunno. Not done it, so can't comment anyway.
