Before, the slope per year was −2.24 (minus 2.25 points a year), now the slope spits out as −0.00519 but if I’m understanding my changes right, the unit has switched from per year to per day and 365.25 times −0.005 IQ points per day is −1.896 per year.
I’ve fixed it as appropriate.

2.25 vs 1.9 is fairly different.
