Bloody hell, that's complicated. You'd need a maths degree!
Just keep it simple: something like 2, C, D, 33, 37. Your feet will be very low. Just try and link the biggest/best holds. Near the right-hand end, you can either go up (easier for a bit, but then hard, dropping down a little) or go low (one crimp doesn't feel that much bigger than a razor blade). Either way, the crux is the right-hand end.
Left Sheff in 2001, so it must be almost 20 years since I've last been. Never had a topo. There are problems but it's a bit small. I never bothered with the problems, just did lots of laps on the traverses. Even when you know them backwards, it's still great training. It's sheltered by a little roof, so you can go there even when it's raining.
Most of the '80s stars went there. It did them a power of good. It's a great little resource. And a very good use of time. Even a quick session there will do so much good.
Enjoy!
