"Up to" is one of those "technically correct", it's probably more genuine and ethical to give a range in the same circumstances. If 95% of binaries get at least 18%. but the remaining 5% get much less than that, and that's important, then say that, maybe.

When i see stuff like this, i usually infer that 95% gets a median of 0% speedup, and a couple of cases get 20.4% or whatever. But giving a chart of speedups for each sort of thing that it speeds up (or doesn't) doesn't make for good copy, i think.
