The TD Skill that you can use to see 2 decimal points of the fuel useage is flawed, because in the race you still see only 1 decimal point.
So if im running 1.96 per lap it might round it up to 2.0
Or it might show 1.9
So the accuracy from practice is useless.
It would be better, when paying for this TD Skill, to see the double decimal points during the race too.
