Tyre strategy

[marcel82]

Now the teams are forced to drive both the soft and the hard tyres during the race, it seems they are using some odd strategy (they all seem to use the same, unless they hit some problems)
Both in Malaysia and Bahrain, most drivers went soft-soft-hard in their stints. (in Australia, no one could tell what compound they were one)

but, when looking on the length of those stints, the stint with the hard tyre is usually the shortest.
For Hamilton, for instance, the second stint was twice as long as the last one (25 laps vs 13 laps)

to add to that, some drivers actually set the fastest lap on the harder compound

so they use the compound that's meant to last for long stints to push in short ones, and the compound that's meant to push in short stints to last for long ones...

or did bridgestone mix up the markings?
