Shaun, I don't understand how folk can say the SS isn't quicker than the Soft - it IS quicker, you've just got to look at practice and quali times to see that it is!
I thought I explained it pretty well really....
In the case of Brazil where 2 cars where on similar fuel load but the soft tyres were 5 laps old and the SS were brand new, from the very first lap of the stint, the laps times were almost identical and the gap maintained at almost exactly 2.5s for 8 laps. The only l difference was accounted for by luck with DRS.
This is contrary to what you would expect in race conditions.
I would have expected an initial advantage to the SS (with current wear I would have thought 5 or 6 laps??) to extend my advantage and then the soft tyre would have started to gain.
