GetAVInfo is similar to GetActorValue and the syntax is basically the same, but getavinfo outputs a lot more information about the given actor value in the console. This function cannot be used in scripts.
In the output you'll see the current & computed base values. In addition, you'll see the values that make up the base value, including the amount from the actor base (i.e. the amount autocalced or entered into the GECK), the result of the derivation function if any, the value as overridden by calling setav if any, whether or not the derived value is added to the base, and finally the three modifiers.
