I was check the chapter to create new races and they categorize Advance a race which have 11-20 RP points but it seems all the races (except the 24 RP Gnome) have around 11-16 RP with mostly Standard abilities.
A power level Standard can have more than 10 RP? Because allowing player to pick the Advanced Ability Score trait for only 4 RP seems quite powerful. This Trait allow a race to have +2 to all mentals or physicals scores plus +4 and -2 to abilities scores of the not chosen type to have +2 to all.
I believe they phrased it something like, "these are guidelines, use common sense when building something".
