As for the PG label. I would never call my son PG outside of a setting that 'knows' Davidson YSP. Inside YSP I say: 'Mildly PG' instead of 'Wildly PG' Outside, I say 'unusually gifted' or 'more than ordinarily gifted' because people who are expecting the behavior of a 'top 5%' kind of gifted will be very confused! I've heard Bob Davidson say that 'Profoundly Gifted is beyond what the IQ tests can measure' and in light, yes, that's my baby.
I really like this way of looking at it. My dd is, again, by some definitions PG, but she is MOST certainly not a Ruf Level 5. There, that drive and personality mentioned above by LilMick, is a requisite.
