Fine, the dips 2018-2019 could very well be noise and we don't dont know if that trend would have borne out after 2020. However, the ACT and SAT composites gradually declined following peaks in 07 and 12, respectively, given the available data.
Come on. Extremely mildly down-sloping if at all, and without anything like an inflection point that would justify "WTF Happened in 2007?"
You can't do this like this. I mean, you sort of can if the effect is big enough (c.f. the 1971 site which inspired this one, and which makes a much better case). But if you can't eyeball a very clear angle in the chart without argument, you need to come to the table with some kind of fitted curve and real research.
