With a softer compound choice here compared to last year, the work today mainly consisted of assessing the performance of the soft, to see how it could fit into the overall race strategy. With Spa being the longest lap of the year, the differences between the compounds are magnified and the difficulty of putting together a perfect lap increases. Conditions today were tricky but quite normal for Spa, with ambient temperatures consistently under 20 degrees centigrade and a track made slippery by some light rainfall, but all three compounds still offered performance in line with expectations and this weather seems set to be representative of the rest of the weekend. We're seeing a bigger time gap between the medium and soft compounds than anticipated so far, which will clearly have an effect on qualifying strategies tomorrow – making it harder to get through Q2 on the medium.
