I'm new, too, but I do know that the numbers on either side of the decimal point represent the genders. I don't know whether left or right is male or female, so hopefully a more experienced member will chime in. For example, 3.7 pastels means 3 females and 7 males. .1 normals is 1 male. Again, I don't know which side of the decimal is which gender. Hope I helped!
