Hi Leonard Nuckolls, thanks for asking. We pull the ‘total_sales’ Product Post meta when populating the Total Sales Product export field.
WooCommerce maintains that record for you, we simply call it and include it in the export. I’ve made a task to add a feature to Store Toolkit to refresh the Product total sales count based on the WooCommerce > Reports section counts but this won’t happen immediately as there are higher priority tasks including finalising WooCommerce 3.0 compatibility across the free Plugin suite 🙂
