I am a member of the BMC and I think that on the whole they do a good job. But when they send me an email with a link to articles about scrambling I would, at the very least, expect the route descriptions to be correct:
"Newbie scramblers beware: despite its lowly grading, Jack’s Rake does require some basic climbing skills. The most technical section – a narrow shoot of upright rock known as Gwynne’s Chimney – will ambush you soon after the rowan tree.
This chimney requires an awkward bridging move,” explains Joe. “It’s very polished and can be wet, but it gives the climber a feeling of safety because you’re in a groove away from the worst of the exposure.”
Unless I am mistaken Gwynne's Chimney is the polished V Diff that starts from the right hand side of the ledge on Jacks Rake? It is definitely not part of the jacks Rake scramble.
