re go down to 3: Use different words and see if you think it was reasonable

roughly 10x going down to 3x would also mean it would go up to 17x. That's a pretty wide range, so I don't think that order of magnitude is going to ever really be similar to 3x of something on the basis of what it means.

but what about a rough order of magnitude? There is definitely some qualifiers you can put on "order of magnitude" to make it include 3.
