"Times smaller", "times less" and their ilk are terrible phrases.
I agree - but if i ever express that, nobody understands the problem. I'm glad i'm not the only weird one!
The issue is how small is it to start with? We can easily express how large something is - there are units for that - but there are no units for smallness. So if thing A is 10 times smaller than thing B, how small is thing B? You can tell me how big it is, but you can't tell me how small it is.
Yeah, we all know what it means - but that doesn't make the illogicalness of it grate any less.
