Common? Less than 5% of the market. Is that common?

They typically don't require any custom one-off parts to be made, just mass-produced off-the-shelf stuff, so they're common enough.

It seems that common means something very different to you and I. Less than 5% of something is common? To me that sounds like the definition of uncommon!
