In reply to stp:
> That's true but hopefully it matters to you. If you come to trad climbing you want to know what counts as a valid ascent and what does not, and what is considered cheating. Without clarity you can't know whether you've succeeded on a route or failed. And what if it is a significant ascent like a new route or a hard second ascent for instance?
Agreed, although to me the question in the OP says more about whether I really want to get a valid ascent of a route or just to get up it without faffing around for ages and boring my partner any more than I already do. For the former, I'd probably want to lower and pull the rope, but in practice if I've got any distance up the route then I'll normally rest on the rope and then keep going - if I really want a clean ascent then I'll come back some other time.
I'd kind of think of this "failed and dogged it before, got it clean this time" as "ground up", despite the rest on the initial attempt, because the first attempt at every move is done on lead with full commitment to dealing with whatever might happen next, and that's the bit that puts the wind up me when I'm climbing at my limit.
> In the pre-sport climbing days things were fairly clear cut. There were three styles: flash, yo-yo (to the ground or a hands off rest), or hang dog (practice the moves but only on your highest piece of gear placed from the ground). In sport climbing things are even more clearcut: its either an onsight, a flash or a redpoint. Nothing else counts.
What about stuff that you've previously seconded in the pre-sport scheme of things? I find that that makes a fairly big difference to how I approach a lead...
