As is said in the title, when mobs drop onto the mechanical belts or the breeze of encased fans, there's a chance that the mob is at full hp (not taking fall damage at all), which is inconsistent since some of the mobs dropped on die. This highly affect the efficiency of fall damage based mob farms.

Edit: it has been tested on moving mechanical belt and the same thing happens
