but to your point, yes, I like to consider what a ball park expectation might be. No way do I put the 5.9 magnum and 3.55's in the truck and be ok with a 17.99 @ 75 mph. Without "some" sort of expectation, then you'd be ok with it. So if 17.99 doesn't cut it, then what would cut it? That would be an "expectation or prediction".
