I agree Chad, I think the soft tyre is probably ok, but the harder tyre may not be hard enough.
Some of the problem may be anxiety on the part of the teams, though. There is less degradation in the races than in practice sessions; Kovalainen only made 2 stops and did the final 22 laps on the harder tyre. Kobayashi likewise made two stops and his final stint was 20. And yet McLaren were telling Jenson to take it very easy to the end on tyres that were 2 laps younger than Kobayashi's were.
