Here is the definition of these two metrics:
Sales revenue/turnover generated during visits which included a load of the analysed element. This is a visit-scope metric and is expressed in the currency configured for the site.
Calculation: sum of the turnover filled in on the main objective pages (changes in order status are not taken into account).
Revised sales (Visits)
Revenue/turnover generated by visits that converted (main goals reached), after order statuses have been updated. This is a visit-scope metric and is expressed in the currency configured for the site.
