If you want a clearer picture I would give it 2-3 months. Than you will see a more accurate picture of latent fun –> real conversion and so on. Furthermore you can see which player value you are getting (if you are working on commission)
To me, the more interesting parameter has always been click –> real, but thats a personal thing.
BTW – for two weeks and just type in traffic 40 RMP seems rather good , is it 1 or many poker rooms?
Good luck
