Misuse of "exponentially". As in:
Bob has 4 tacos.
Mary has 7 tacos.
Mary has exponentially more tacos than Bob!
Uh, where the x-axis? There's one frickin' data point.
(and yes, I made up that example, but I see it all the time with other things in place of tacos.)
I need to get back to packing. Down to the last 10% taking 90% of the time, I bet.
