Heavy Flavor Averaging Group (HFLAV) methodology and latest results

The Heavy Flavor Averaging Group has for the past two decades formed averages of measurements involving the properties of b-hadron, c-hadron and $\tau$ leptons. The averages are taking into account direct as well as indirect measurements of properties and are updating external constraints to include their latest values. We will in the presentation outline the averaging methodology used and highlight new results as well as instances where the more in depth treatment of indirect measurements and correlations leads to big differences with respect to a naive average.
