If you don't really care about whether you actually summit or not that's fine. I've done a lot of routes where the interesting climbing stops a few 100 feet from the summit and I don't bother finishing it off but those are climbing routes not summit attempts.
When you fly into some unclimbed peak for the purpose of doing a FA and are 100 yards away, if you want to tell everyone that you did it spend the extra effort to run up there. 100 yards should take what, 20 min at 8000m and 5min at 7000'?
I just don't get why someone that's so excited to tell everyone that they're the first person to climb a peak, wouldn't put in 5 min. to make it a reality???
