This holds in particular for the $L_\infty$ norm, where we evaluate the maximal deviation of numerical and exact solution only at the quadrature points; one should then not try to use a quadrature -rule with points only at points where super-convergence might occur, such as +rule whose evaluation occurs only at points where super-convergence might occur, such as the Gauss points of the lowest-order Gauss quadrature formula for which the integrals in the assembly of the matrix is correct (e.g., for linear elements, do not use the QGauss(2) quadrature formula). In fact, this is generally good
