So whats the difference between it being in a gerry can, or in the cars sealed fuel tank with none getting out?
Sweeny, its not infinite either, it's actually 'nothing'...but expressing that in the form of a number isn't 0 and it isn't infinite, and it certainly isn.t 999mpg.
Do 3 miles at 50 mpg, coast down a hill at apparently 999.9 mpg and the average is then 287mpg.....when its not. Its 50mpg as you can't count something you're not using!
The joys of mean, modal and median averaging...
If you used median averaging then yes, it'd be skewed. If you used mean averaging, it'd be a bit screwed up.
That's why it uses modal averaging.
