guess all of mine have had 1.0 at the beginning then. usually finish a trait, make a serum and go find a dump girl never really paid attention if it was 1 or not just that when faults lowerd. never mastered a trait in research.You can't make a serum (to give to girl) without at least 1.0 mastery of the trait. Then when you have the serum with that trait you can give it to a girl for testing
