Agreed. Despite managing my first 6A, 6A+ and possibly a 6B in the forest last month, I failed miserably on the blue circuit at J A Martin on the last day. Eventually, I picked up my doormat and pottered around flashing all the oranges I could find... which was pure fun and often as not, quite nerve-wracking considering the topouts with no pad below.
The 6th grade problems I managed, I climbed and had no idea of the grade untill I checked Bleau later. Maybe in the higher grades Font is for pushing grades but down in the bit I inhabit, it's all about getting your arse kicked and just climbing lots.
