In reply to tommakin:
It is important not to get too distracted by personal difficulties / issues because as we all know - grading IS an exact science. All of the route setters are Scientists - and they NEVER make mistakes. The routes will always be graded EXACTLY at their specified difficulty (+/- a facial expression or two). If a route feels too hard or too easy, it is inevitably the result of:
high / low gravity
excess / lack of alcohol
phase of the moon
audience
It is also very important to acknowledge that perceived difficulty is never subject to "humidity", "temperature", "belaying", "crowds", "queues" etc. - such that everybody attempting the routes in any of these events is absoultely fairly and equitably treated.
But........ did you try the 6b at the Foundry 2 years back!!!!!!!!!!
