With the benefit of both hindsight, and not being responsible for the strategic decisions which could cost millions of pounds of revenue, we may all be able to make better decisions than the McLaren pitwall. I think the question that should always be asked is why didn't EVERYONE pit on lap 38? I could see that the slicks were better (I could see that for a couple of laps before anyone stopped) - yet no-one had made the gamble. It's not just McLaren who waited, but McLaren, Ferrari, Sauber etc etc... Yes, LH should probably have stopped a couple of laps earlier, but then so should everyone. This wasn't a case of LH being kept out because Button was pitting - they showed in Melbourne that they could double shuffle when there was a gap of 10 seconds! This was a case that they believed that the best course of action was to keep LH out - in the hope that it might rain. When Vettel got into striking distance, they had to pit him to keep track position! The only sequence of events that would've given LH track position over Alonso was if he stayed out longer, it had started to rain, and he'd been able to make 1 stop from worn inters to new inters, whilst Alonso had made 2 stops, worn inter - new slicks - new inters... Since the rain didn't come, this wasn't workable!
