There were no real surprises from our point of view in free practice, as we made a number of track measurements before the start of the weekend that gave us some indications of what to expect. The tyres all have a tread that is 0.4 millimetres thinner than before to avoid overheating and blistering here, and so far, we have seen that this has worked, without compromising tyre life either as degradation here on the new surface is quite low anyway. The track has been used a lot since the new asphalt was laid and it's lost a bit of the sticky surface bitumen, which means that grip levels have been more variable than before. Today, drivers have also been affected by the wind altering the aerodynamic balance, as is often the case here, which made it difficult to find the right braking point; but in the end the gaps at the top are quite close.
