In reply to 1poundSOCKS:
> I think you tend to learn best when you're not stressed. So for most elements of climbing, placing gear, technique, tactics, etc, you'll get more benefit, especially as a beginner, from mileage at a fairly comfortable grade. You can learn by pushing yourself, where a fall is more likely, and you can learn from falling, but I think it's best to learn other skills first (especially placing and assessing gear).
^^Agree with this.
But you can still push yourself without falling off. I fail on routes frequently, but only occasionally fall off. Quite frequently it's getting so pumped that there's no way I can do a move and I rest on the gear. It's all very well saying that in that situation you should carry on 'til you fall off, but very often I just can't do the move (but I can scrappily retreat to the gear). I also back off routes when they're too hard or bold.
So, if you don't know where your limits are because you've never pushed them, then that's not good, but that's not the case here (the OP). Only when you really need to put every last bit of your physical resources into a route e.g. redpointing, hard (E5+?) trad does falling off crucial to improving.
