Reference Erietech's last illustration where he denotes "crawl space insulation". The two lines he drew for that insulation and rafter insulation bisect in a soffit area. I suggested taking his rafter insulation below the top of the crawl space insulation into the soffit area.
If he had soffit vents he would want to install insulation channels first before insulating. No vents so moot point, filling in any infiltration area with insulation is ideal.
