Blend Glitch working

[test]

Does anyone know how work the Blend Glitch( mix option)? I realized that the option "C" removes transparency in the application of mixes each other. But I do not see any difference between "A" and "B" mode.

Everything is so secret ? Or no one knows how it works?

My experience seems to be that A is standard, B is more of a power curve on the opacity and C makes it so if you fade between 2 layers of white, you see no change in level.
