I didn't guess a number for my daughter per se, but I knew my IQ was somewhere in the mid 140s and I knew that she was smarter than me, certain things she did would just astound me. When she was 4, we signed her up for testing for a preschool gifted program. They spend 10 minutes and asked questions about animals which she couldn't answer (They should have asked her about tools). The didn't have her read or anything and told us her IQ was 115. I knew that was wrong. Her school takes the OLSAT and that came in the high 130s in 1st Grade and I knew that was wrong. 3rd and 4th grade it came in at the high 140s. Knowing the compression on that test, and needing more ammunition to advocate for her,even with my husband(her unbelievable EXPLORE scores weren't enough, which actually was the point where I was actually blown away and a then a little scared), I finally had WISC-IV done. Her GAI was 155 which made much more sense to me given what i had seen and here we are getting started with DYS.
