Trinidad has a PISA score of 410
IQ = 100 - 0.9 x 15 = 86.5
Trinidad is 60% black @ 85 IQ
Trinidad, Nishad Indian IQ = ( 86.5 - 0.6 x 85 ) / 0.4 = 88.75 IQ
Mauritius has PISA score of 440
IQ = 100 - 0.6 x 15 = 91
Mauritius is 5% Euro, 30% black and 65% Nishad Indian
Nishad Indian IQ - ( 91 - 0.05 x 100 - 0.30 x 85 ) / 0.65 = 93
One factor pushing it up here is that the entire 65% is not Nishad, but rather a blend of 50% Nishad and 15% Dravidian
