Pit Stops

Can someone just clear something up for me, The last race is 4.8 litres a lap. the assistant says that PLUS i checked the end result and it turns out they were stop on.

BUT on lap 10 it says i have 4.7 litres of fuel in the tank

i come in to pit and add 53 litres

but at the end of lap 11 it says ive got 48.2 litres of fuel in the tank, thats 9.5 litres used on the out lap!!!???

This happens again for the other two pit stops.

WTF? lol

1/ The technical director will be wrong
2/ The fuel is worked out as you cross the finish line regardless where your pit box is [ie. if your booth is before the line it will look like you pitted 1 lap after you actually did

example say 5l a lap and you put in 30l when you pit

LAP 10 - 11l
LAP 11 - 6l
LAP 12 - 1l [This is when you are pitting & you pit box is past the start finish line]
LAP 13 - ~25.5

LAP 10 - 11l
LAP 11 - 6L
LAP 12 - 29.8l [This is also the lap you pitted, but you filled up before the start/finish line]
LAP 13 - ~25

Although if you post a screenshot of your exact result i will be able to explain better

Considering 9.5 is double 4.7/4.8 i'd assume it's what David said.

wow i never knew how in depth it was. cool cheers!
