Sergio Perez has been repeating at Force India the sort of drive he became renowned for at Sauber, running long stints, looking after tyres, achieving surprising results from midfield grid positions. But at McLaren, he didn't do very much of that at all, and I think we need to ask why.
It seems to me that McLaren only understand one tactic - the undercut. They don't always get it right, because the pitcrew are not all that reliable, but at least the timing of the pitstop is normally OK. But when the undercut is not relevant, they are completely lost. I was hoping that might change under the new regime, but so far, it's not happening.
In Austria, McLaren did a good job of timing Kevin's first pitstop to prevent the attempted undercut by Hulk, and they did the same at the second pitstop. That way they stayed out as long as possible, to shorten the following stints, without losing track position. Also, Kevin was well advised not to try to pull a gap, as that would have led to increased degradation and spoiled the strategy.
Jenson was in a different situation. Starting on primes, he obviously needed to run a longer first stint. But how long? One can almost imagine the fidgeting in the McLaren pit: "are we there yet?". Some good judgement was going to be required.
The problem was that Jenson was a little bit less than a full pitstop ahead of Kimi's Ferrari. He was not gaining ground, and he was not losing. If they pitted him, he would come out just behind Kimi. But it wasn't a bad situation for Jenson, because each lap that this persisted was helpful to Jenson, and a problem for Kimi. The longer Jenson could delay pitting, the older Kimi's tyres would be when Jenson came out on fresh rubber.
Of course, if Jenson's tyres had started to really go off, and his pace went away, then if he didn't pit immediately he would come out further behind Kimi, so he would have to close that gap before being able to attack. But even that wouldn't be a real problem, he would still have the tyre advantage. Basically there was nothing to be gained by pitting Jenson before he started to struggle for pace, and there was even a good case for leaving the pitstop until later than that.
So why did McLaren pit Jenson on lap 27, knowing full well that he would come out behind Kimi? Presumably they hoped that Jenson already had enough of a tyre advantage, so that he would be able to overtake Kimi fairly easily. After all, he'd done some overtaking in Canada. But this was a different circuit, and it should have been clear by that point in the race that you needed a big speed advantage to overtake at the RedBull Ring.
Please, guys, get yourself a strategist.
