In this paper, we apply Fedder-type criteria for quasi-F-splitting to provide explicit computations of quasi-F-split heights for Calabi-Yau hypersurfaces, bielliptic surfaces, Fano varieties, and rational double points. We also find interesting phenomena concerned with inversion of adjunction, fiber products, Fano varieties, and general fibers of fibrations.
