      * A VariadicGridFunctionLocalOperator takes multiple LocalFunctions, an implementation class,
-     * the differentiation order of the operator and the LocalFunction polynomial
-     * degree, to calculate the quadrature degree of the operator
+     * the differentiation order of the operator and a user-provided polynomial degree,
+     * used as the degree of the LocalFunction to calculate the quadrature degree of the operator.
+     * Usually this should be the maximum of the degrees of the localFcts. If `localFctOrder` is `-1`, 
+     * we try to detect the maximum polynomial degree from the local function implementations.
