So the "most typical" UPP is C550550-9?
It is a bit trickier than that, as Hydro has additional DMs based on factor of Size and Atmosphere. (If Size is 0 then Hydro is 0; if Atmosphere 0, 1, or A+ then -4 DM Hydro roll.)
These extra conditions increase the odds of a Hydro 0 world.
But a world of Size 5 and Atmoshphere 5 will be weighted to have a Hydro of 5.
