In reply to CurlyStevo:
Not sure where this line of enquiry is going (i.e. I'm not sure it'll turn up anything very ground breaking) but here are my stats anyway.
Indoor RP - 7a+ (3 or 4)
Indoor Onsight (or flash, if you prefer Monk!) - 7a (2 or 3)
Outdoor RP - 7a+ (3)
Outdoor Onsight - 6c (3)
Outdoor Flash - 6c+ (1)
I don't top rope anything indoors or out so I can't contribute anything there.
I haven't ever really seiged anything indoors or out either. The longest I've taken is 5 goes, over 2 sessions to get my first 7a+. Other than that I've done all my redpoints 2nd or 3rd try.
Onsighting is the big difference - it's so much more difficult to read a good sequence and make changes to it on the fly when you're outdoors. I would expect to onsight 100% of 6c's indoors but out of the 15 or 20 I've done outdoors I was only successful on 3 occassions (and almost all of those I went on to do easily 2nd go).
I think indoor onsighting is probably closer to a beta flash outdoors. Case in point I've only ever attempted one 6c+ with beta and I was successful (normally I climb with my wife who climbs a lower grade than me so I'm usually the one to go first up a hard route).
