| EMWs are calculated for each country, using the method described by Mood et al. (2023). EMWs are preferably based on average weights, preferred weights or simple weight ranges. Such data for the same country whose numbers are being estimated, or otherwise data for country with the highest production tonnage, are used in preference to other data (where possible). Common weights and weights from marketing websites are used where average weights, preferred weights or simple weight ranges were not obtained. |
