I guess that is right. Hard to guesstimate distance but if you know the route hands reaching left for good hold at the end of the difficult layback section on vector to end of fall inverted, feet level with the overhang you come round, head 6ft below!
It was huge surprise to me to go so far with a runner at chest height. My only other longish fall was left wall, same ropes, maybe 100 ft rope out, gear 2ft below feet estimate went about 20ft landing neatly back in the niche! That one was as far as I expected to go. This one I had time to think 'shit I've fallen, shit the gears pulled, no I can see it is still there, rope must have cut.... Boing!!!'
I will just avoid climbs with traverses and belayer round the corner.
Thanks for all your ideas everyone.
