My point is that if you group these tests into pairs, (1 and 2) and (2 and 3) seem to correlate without much help but (1 and 3) is different, it has a suspiciously large amount of human effort invested in strengthening the correlation.
I don’t know what you could mean by “suspicious.” Maybe there is a large amount of human effort invested in strengthening the correlation between 1. and 3. What would follow?
