Since madVR FRC blending is variable each VSYNC, the blending percentages between video frames are better visualized like the following:

Thrown together quickly and not very exact, but the point is that unlike traditional blending, you'll have custom blending ratios each VSYNC based on your refresh rate VS video timestamps on a global optimal timeline. If your 30hz refresh rate or video timestamps are non-perfect, you'll likely end up with all video frames being blended to some degree because of misalignment. madshi generally recommends using at least 60hz refresh rate (the higher, the better) to cut down on the number of heavily blended frames and the blurriness they induce.
