There's still a number of people that would like to being back refueling, for me I could take it or leave it, on one hand it would be great to see the cars going flat out in short sprints but on the other hand the less overtaking we can see in the pits the better.
Anyway, it got me thinking, how on earth did teams calculate what was the best strategy for a particular race and for each driver? As we know they qualified with race fuel, depending on the circuit you could find an advantage on qualifying lighter and vice versa on other circuits. In theory it is better to start heavier and then make up that time when others pit, but as you know dirty air can put a spanner in the works along with many other scenarios, the engineers back then were certainly earning their wages.
