Speculation.

People believed that X:Y was 2.2:2.0, but it's now 3.15:2.05.

The 10% EROI apparently wasn't impressive enough, it's now 54% EROI on paper (assuming less because of capture inefficiencies).

I'm no expert, but theoretically my understanding is that this ratio should scale along this same pattern for higher values of Y.

The X:Y ratio should increase for high values of Y in ICF. See https://suli.pppl.gov/2019/course/SULI2019_IntroICF_TMa_2019...
