because the model need to find the path to accelerate and more precise statistical Time to Time. The Time , use unity's own navigation pathfinding module, found in the acceleration (Timescale=10), the Navmesh. The destination is not a frame of a frame of computation, such as the rate of 1, coordinates should reduce 1, 10 times but actually for the output of mobile 10 times the distance and Time, in the middle of the 10 steps will not calculate, a bit don't understand this aspect because what reason, specific can see below the results
====================================================================================
This is 10 times faster the Z coordinate of the object changes, it can be seen from 90 to 80, but not 89,88,87 reduce, but to calculate the speed of the last frame,
