Just a simple NEM newbie question: The importance is something like 1%oo. So I guess it does not mean that my importance is 1% because my stake is much to low for such an high importance

What does it mean instead? 0,001%?
NEM uses the "per mille" system for it's importance score- Edit: Sorry, It uses the per ten thousand system -

The per mille system was used in previous betas we tested.
