Any way to find error from the stack profile tool?

I used the stack profile tool within the 3D analyst to map elevation changes on the surface of a glacier.  Wondering if there is a way to get an error assessment of the graph?

Also, how the stack profile tool works exactly, if I used a raster, does it take a value at a certain interval or just across each pixel.  Different rasters put under the same line have different numbers of actual point measurements.

From this link,.... this is pretty well all it says.

The output table provides the information needed for generating the profile graph. Each line feature is densified along its overlapping profile targets in a manner that captures the profile's characteristics by introducing new vertices along the line. The elevation and distance along the input lines created by this densification gets stored in the output table along with the additional information about the line features and profile targets. The values in its fields can be used to create graphs in a wide variety of external applications. The fields represent:
