Jan, thank you!

Clearly I misunderstand how open list PR usually works.

Yet I'm still confused.  Wikipedia doesn't seem to clarify what 
"preference vote" means.

Specifically, this article ...

https://en.wikipedia.org/wiki/Open_list

... refers to "preference vote" but does not have a link.  It does link 
to ...

https://en.wikipedia.org/wiki/Elections_in_the_Czech_Republic

... and that article has a link named "preference vote" but the link 
goes back to the "open list" article.  (Sigh)

When I search for "preference vote" Wikipedia sends me to this article ...

https://en.wikipedia.org/wiki/Preferential_voting

... which lists multiple articles that relate to this term, none of 
which seem to clarify what it means in open-list PR.

Can someone here can remedy this issue on Wikipedia and then point me to 
the fixed article?

I think this approach would be more efficient than writing an 
explanation just for this election-methods list.

If not, a brief clarification here will be helpful.

Thanks!
