Average yield from hop vines

I know that this is a very difficult question to answer and yield varies widely and wildly but as a new hops grower, I have no idea what to expect in terms of how much hops I will end up with. What is the yield range per plant? I have 4 rhizomes planted. I know that I won't really get much until next year but, can I expect half a pound per plant (dried)? or much more, or much less? I have no idea. Can you give me some idea? thanks in advance.

A half to two kilos, dried.
