I'd guess there are a lot more unrecorded climbs on UK rock though. I mean, if you go and bimble up something obscure and, honestly, utterly un-noteworthy while you were tramping across the middle of nowhere one weekend, you might just not bother writing it up anywhere.
But if you went on a Greenland expedition, it's a pretty major event and climbing any of the peaks is going to be something you properly plan for, then execute and seems noteworthy at the time, I would think.
So in the former example there will be plenty unrecorded due to lack of quality, too much quantity or just plain apathy but none of those reasons seems likely to apply to Greenland peaks, so it would only be the desire to deliberately obscure one's ascents that would apply.
