I have only summitted once on three trips to Welch Peak. Truly, I am so suck
In general, failure on a peak either indicates a willingness to attempt things in marginal conditions, or a low skill level.
Let's say, though, that you go in to attempt an unclimbed route and climb an easier, already climbed line instead for some reason. Does that count as "failure" or "success"?
Conversely, you try and climb an established route but get off route and inadvertently establish a new route. Did you "succeed" in climbing a new route or "fail" to climb an existing route?
