Magento 2 Hyva CRO extension for increasing the purchasing confidence by adding a "Customers usually keep this item" block when the item has been returned less than a configured threshold return percentage.
composer require elgentos/magento2-hyva-cro-purchasing-confidence
bin/magento set:up
You initially want to run the calculation crons manually, so you have that data. The updating of the return percentage on a product basis happens monthly, the recalculation of the average return percentage happens weekly.
