A comparison of LEP measurements, with emphasis on the final ALEPH measurement with leptons, and a critical discussion of average from heavy flavour electroweak combination is presented.8 pages, 5 figures, to be published in Proceedings of "XXXVIIth Rencontres de Moriond - Electroweak Interactions and Unified Theories", Les Arcs, 9-16 March, 2002High Energy Physics - Experimenttext
