Again, I wasn't talking about what's it in "proper english" -- but how it's used in benchmarks.
Kevin Decker, who did the site in TFA, is a native english speaker, and yet he writes "1.5x faster" to mean baseline1.5 (and not baseline + 1.5baseline).
So clearly it's not so "unambiguous" whether you can use faster in this way or not. And in fact, I've never seen any of those benchmarks where "Nx" doesn't mean the final value is N*baseline.
