I'm not a mathematician, but 7.02% is hard to see from these figures.
------------------------------------...
Test Run Average MPG Average MPG
(without Jetstar(TM)) (with Jetstar(TM))

1 7.96 8.49
------------------------------------...
2 7.62 8.46
------------------------------------...
3 7.45 8.52
------------------------------------...
Total Avg 7.68 8.49
------------------------------------...
Now, isn't that a 10.5% average increase? (8.49-7.68)/7.68. Or to look at it another way, 7.68+10.5%=8.486.
Someone correct me please!
