From the very beginning of coverage, it was said that those on a 2-stop strategy would need yellows. Then there were no yellows. But then suddenly everyone who had pitted only twice was fine to get to the end, despite no yellows. ????? And don't tell me they were conserving fuel - no one was able to catch the leaders at all so they couldn't have been conserving THAT much. So I ask you, how did so many teams miscalculate the need to stop 3 times? If there were no yellows (which was the case), you could make it on 2 stops, as we saw. And if there HAD been yellows, well then you surely could have made it on only 2 stops. So why did so many pit 3 times??
