Biome Densities/Weights

Hey all,

I think myself and quite a few other people have probably been wondering this for quite a while now, but what is a normal biome density/weight? I usually set mine to the maximum (1024 in case you don't know) to test it, but then I want it back down to a normal rate for release. I've just made a rubber biome (because, interesting factoid, rubber comes from the sap of a certain kind of tree) and I want it to be about as common as a birch/oak forest biome. What number would I put in for the weight if I want it to be that common? What about if I were to want it to be about as common as other biomes? What is the biome weight of each biome? Is there a chart somewhere for that, or something?

Thanks,
