Abstract The theoretical description and data for inclusive semileptonic B decays have reached incredible precision. This motivated us to re-animate the discussion of possible Quark-Hadron Duality violations. There seems that there is currently no evidence of a failure of the Heavy Quark Expansion (HQE) used to compute observables for these decays. https://www.diegojavierfares.com/hot-price-U-S-POLO-ASSN-Blue-Cotton-Men-Sweater-p18350-great-buy/
