Well some people understand something. You can watch a video in youtube about how LSD (limited slip differential) works for example. Basically normal LSD or viscous differential (type of LSD) don't do torque split, they only redirect torque when other side of the differential is spinning faster than other. In other words they distribute more torque/power to the slower side than with open differential. The stiffer the differential is (higher value) the more power is redirected to the slower side. If there is no speed difference between sides, the torque split is simply 50:50.
