This kinda raises more questions over the last series as i dont do many pitstop races. So in S1 was the pitstop a fixed length? It always seemed to be 30sec but then i changed tyres and fuel, felt like a no brainer as i assumed the time spent was fixed. And i can see doing something different that the same 90min races will help not be too reptetive Yes i was initially worried after thinking about my Spa usage and i didnt think the it could fit 75mins into it. But then it is a long lap and you might not see the same usage rate on these tracks.
