Gas Giant Presence and Number
Just a thing I've noticed about the gas giants in system and worldgen.
In system generation, a gas giant is absent on a roll higher than a 9, or 1 in 6.
Later on, when determining the number of gas giants, you roll (2d6/2)-2 (drop fractions) yields 0 giants on a roll less than a 6 which is 5 in 18. Is there a type of gas giant that doesn't count as a G in the PBG rating, or is the formula off? (Switching it to 2d6/2-2 round up makes the chance of zero giants match, but if there's a giant that doesn't count in PBG, there's the place for them.)
Any thoughts?
