I agree with what HK said, I think knowing why you need the number is very important before testing. For me, we don't have an "obviously gifted" child - that combined with a good dose of imposter syndrome from her parents AND living in the most modest of cities in modest little NZ meant that I would have the data to back up getting her needs met. I just didn't trust myself to advocate without it.
As for what LOG that is purely for DH and I, we both research the hell out of everything so this was just another bit of info to throw in the mix. It also does help put things into perspective at times to see where along the curve DD fits when other parents are comparing her to their MG or NT child. I haven't come across a PG child yet (that I know of!) Although due to the great news over here right now there has been a lot of reporting on teenagers doing amazing things in school, so I know they are out there.
