If you are training for tough rides like Mulholland, Breathless, etc. then what jmX said, 100' per mile, is a good benchmark to chase. My best for a single ride was 286' per mile, but that was a one way climb up.
I'm in the anti-strava camp. Probably because I'm too damn slow to be competitive on any of the climbs. But also because the crazies chasing strava records (both on and off road) make life dangerous for other road and trail users. I think Strava should ban downhill on road segments and all off road segments. Trail access fights are tough enough without giving anti-mtbers even more ammo.
