It basically comes down to the landing distance, the effect of the tailwind and the reported braking action. Given the figures there, I've just gone off a standard 60T aircraft with 10kts of tailwind and there's only one solution that we will be able to stop in the landing distance available. It's Flap 40, max autobrake and the reported braking action being as good. Anything less than that and we wouldn't be able to land there even with a 10kt headwind.
So back to the question, I would continue (given the solution above), if I floated or was going to land outside the markers it'd be an immediate go around. The latest point in which we can go around is up until we select reverse thrust, so lots of opportunities to bug out after the landing clearance.
If ATC had said "wind 260/11 runway 08 cleared to land" I'd be out of there.
