We discuss our methods with a special emphasis on accuracy and reliability. We establish numerical equivalence of Wilson-Polchinski flows and optimised renormalisation group flows with an unprecedented accuracy in the scaling exponents. Our results are contrasted with high-accuracy findings from Dyson's hierarchical model, where a tiny but systematic difference in all scaling exponents is established. Further applications for our numerical methods are briefly indicated.9 pages, 7 figures, comparison and discussion/conclusions sharpened, references addedHigh Energy Physics - TheoryStatistical MechanicsHigh Energy Physics - Phenomenologytext
