Do you know what the phrase “order of magnitude” means? Half is not an order of magnitude so your math proves my statement correct. From wikipedia: “ Orders of magnitude are used to make approximate comparisons. If numbers differ by one order of magnitude, x is about ten times different in quantity than y. If values differ by two orders of magnitude, they differ by a factor of about 100.”

I will excuse you, despite your rudeness, but next time Google the phrase you don’t understand before accusing someone else of ignorance and then going on to show them they are correct and that you don't know what simple terms mean.
