Cell size on cost path calculation

Hi All,


I have a basic question about cell size (i.e. in meters of my calculation; 30 meters compare with 300 meters) on cost path calculations.

Is it true, if I have smaller cell size of cost surface will have bigger cost path values?

In my understand the smaller cell size will have more accumulated cells of cost distance, and vice versa.


I still don't understand this paragraph at [1]:

When the input source data is a feature class, the source locations are converted internally to a raster before performing the analysis. The resolution of the raster can be controlled with the Output cell size parameter or the Cell Size environment. By default, the resolution will be determined by the shorter of the width or height of the extent of input feature, in the input spatial reference, divided by 250.
