In reply to Pete_Mosely:
As far as I can tell, the ending position of the arrows in the BMC guide is pretty arbitrary. It doesn't indicate the top of the problem. The arrow symbol seems to suggest that you should continue upwards...
If you look elsewhere in the BMC guide, you'll see that bouldering venues like brownstones have arrows finishing at all sorts of different heights, even though all problems there top out.
For the easier Longridge problems, they do mostly go to the top, though whether you think the final metre is worthwhile is up to you. Where I've drawn a line to the top, it's because that's where I thought the problem went. There are other problems at Longridge which I've shown as finishing at obvious breaks (and where it's most likely the FA went all the way up, but this is no longer normal).
