Ok. His mean in comprehension was 17. In the other two VCI subscales they were 15 and 18. Apparently, the comprehension score was high enough to pull all the scores up to 99th for the VCI result.

Does that 17 look like a ceiling for his age at the time (8.4 months)? I've seen it said that is 3 standard deviations above the mean.
