I'm not sure I'm following your point....

If you calculate that under the best conditions the runway in its current state will only have a 30 foot safety margin, you don't land on it. You either circle and wait or go somewhere else....

" change the way they calculate stopping distances "

Somehow my brain just glanced over 'change'.

Specially if, typically, most pilots can't land within 30 feet of where the intend to land in the first place.

Ever seen the length of runway at most aiports with all the black marks on it?

Must be at least 500 feet!
