its about specs.
you can say its a 96 liter limit.
or you can say its a 95.75 liters +/- .25 liters
means the exact same thing. its a 96 liter limit. the rule has the tolerance built in.
so saying oh man, its only .4 liters too much that has no effect. totally true, likely didn't have any effect on the race (unlike the refueling time, which could vastly effect the outcome of the race). but its a 96 liter limit, not a 96 liter +/- .5 liters, or a 96.5 liter limit. its 96. you go over, your penalized.
