One other point - oh statistically naive one:

A phrase such as "will have gone up by 92%" is also meaningless unless you know the effective base line from which that increase is measured. In other words - "gone up from what?"

You can say, with some truth, that "this basket of apples has gone up by 500%!" What - from 1 apple to 5...? If the initial base line from which the increase is measured was low - the vaunted increase may not mean that much.
