probably we should compare MS lap times before overtaking Button and after. If he slowed down a little bit that could mean that he wanted to see RB emerge before him on the track after his third pit stop. If not then RB has clearly beaten him, because a comparison of their lap times showed there was very little in it. Both cars slowed in the final laps, but that did not mean that RB couldn't have gone faster.
