Floor 4 pvp requirement

Says i need to maintain an average pvp score or i'll get dropped back to floor 3.
How do i know whats the average? Cos i ignored pvp after getting to floor 4

They should add an indicator or something showing your score compared to others with a percentage on how high you are..

i think 1600 score should be more than enough

I've been on floor four for over 4-5 weeks now and I've need gotten above 1700 point in pvp and that has always been enough to keep me on that floor. I've even heard of guys trying to get demoted by having as low as 1100 points and still not being low enough to get demoted. I think you'll be fine no matter what.
