4 hours is not much, I don't think enough people have seen you yet.. I think you should play a little longer..
I had 2 when I applied.
Anyway, still try to improve the playtime abit, as when I for example applied when I had 2 hours, the server was only up for 2 hours, so I already knew everyone, just try to get a bit more known in the community and server.
You got enough time to do so.
