Please add # of sales per last week/month/quarter/year/all for to the api tracking data. Right now the only sales data we have is avg_sales and avg_revenue in the last 4 weeks. The web interface does include relevant data, unfortunately the api does not (yet). In my opinion there is no need to push averages and revenues through the api. As long as prices and # of sales over different periods of time are available then api users can calculate these numbers themselves (and more).
