    "abstract": "We prove a powerful scaling property for the extremality condition in the\nrecently developed variational perturbation theory which converts divergent\nperturbation expansions into exponentially fast convergent ones. The proof is\ngiven for the energy eigenvalues of an anharmonic oscillator with an arbitrary\n$x^p$-potential. The scaling property greatly increases the accuracy of the\nresults.",
