“Significant” Object Attribute Differences

SAV also compares a set of attributes by using special heuristics specific to certain attributes, so that differences SAV considers “significant” is shown.

If an attribute value in one of the snapshots exceeds a minimum (or maximum) threshold and its value changes by at least a certain percentage between the snapshots being compared, then SAV presents this in the comparison results.

The following table shows special object attribute differences.
