I just raced in Bahrain today whereby the temp was 36c and all those (inc myself) that used SS qualified ahead of Softs.
That one can be explained.
The tyres straight out of the box, start towards the 'cooler' temperature range on the tyre guage (like when you refit tyres during a pitstop) Even with Push Level 3 for Supersofts in 36C Bahrain, the tyre will only really start overheating in Sector 3, which only has 2 real corners, rest straights.
Normal advantage is -0.900s/lap to -1.000s/lap from Supersoft to Soft, and the average gap was around -0.700s, so +0.200s to +0.300s was lost to overheating in those 2 corners.
Okay but how do you or anyone else for that matter explain what happened in the link I provided? Also how do you explain the qualifying time of those 2 drivers who qualified in 5th and 6th with a huge disparity in mental stats in the race that you saw my team race today?
Out of interest, could you give a scenario whereby the Softs should qualify higher than SS with car and driver stats being equal?
