It's 99% correlated (in line with) the longer test method. OK. Then you learn that there were 77 in the study. So they got the result wrong 1% of the time, for 0.8 of a child?

Shenanigans.

"the two tests have a 99% correlation"

"they recruited 77 gifted children through"

[yes, it could be a rounding error]

That's not at all how correlation is measured.
