Some additional information - it seems indeed that we have been looking at raw data - as these are specific to each test and therefore not comparable, therefore their publication as such may have been meaning- and therefore pointless.
More interesting are the processed data, read IQ estimates - and the variance thereof, pointing to some bias caused by DD's visual problems - which, once corrected, should push the total a bit further, well beyond the three sigma already touched now...
On the other hand, I have some doubt about the reliability of any scoring methods beyond plus two sigma, as the statistical evidence gets thin.
But all this distracts from the real issue at hand - how to organise proper schooling for DD.
