These things are contextual. "x increases three times" means 3x to most people. This is different from "increases by 300%" which usually means 4x. The article says "by a factor of up to three" in the first sentence but that is too wordy for a headline. > what happens if 30 “increases by 1 times”? Nobody would ever say this. We would say it doubled or stayed the same, or "increased by 100%" perhaps, but never "increased by 1 time". > 30 “increases by 2 times mean?” Nobody would ever say this either.
