Probably different push levels for the stints he was able to squeeze more out of it. I have an excel spead sheet with all the formulas, it doesn't lie as to the fact of what a fuel load is for the amount of laps it gives. The fuel is wrong.
Also I don't know where his pitstall was, like where exactly he was clicking by the s/f line because that is when it gives the fuel remaining reading, so the the "driver" might have seen that it would have had about 0.1 for another lap or less (around 3.8L usage on 5/5) and that is cutting it close. So he came in with 3.9L A lower push level on the third stint is probably how he got an extra lap out of it.
But it still stands, his fuel was way off. He went 10 laps on 37L. He tried to go 18 laps on two 33L stints.
with max push and max kers its was 3.7 ltrs per lap, and he had 3.9 when he crossed the line, there is no push level that exsists to do 3.8 or 3.9 per lap in that race..... he had enough fuel, he clearly likes to push it yes but thats how u find the extra's tenths throughtout a race that makes the difference agaist your rivels, his fuel was ok.!!!!!!!!!!!!!!!
if every lap was 3.7 he would of needed 33.3. ltrs
if every lap was 3.6 he would of needed 32.4 ltrs
but most laps are 3.6. he had 1 or 2 x 3.7 laps per stint
even if u put a safety of 5 x 3.6 laps (18 ltrs) & 4 x 3.7 laps (14.8 ltrs) = 32.8 ltrs for that 9 lap stint and he had 33. (and he only had 2 x 3.7 ltr laps in that stint which would leave plenty to finish the next lap)
and if u read what he wrote he was not even on max push for that lap were it pitted him early..
