This was the race:

He pitted to change tyres and refuel, and 3laps later, still with 27L of fuel and 76% of tyre condition, pitted again to refit the softs.
Then, when I got home and it was the last lap of race, and I mean, 30Laps for singapore, and it was already lap 30 and my driver was going to pit unless if i had not press the button that was saying "pitting", and then he finished the race with no problems, and with, guesss it: 13L of fuel and 48% of tyre condition.
Thanks.
