hoping for a huge quarterly update!!, page-8

Last sep quarter they claimed revenue over $1M with cash receipts less due to cash received for orders in prior periods.
Dec quarter once again claimed rev over $1M, operating profit around $400K and cash receipts of $237K (also shipping $900K of product early in the next quarter).
Last quarter they state cash due $850K, and cash received of $190K. Revenue recognised from RBCGO of $450K (when will the cash follow?) If cash receipts are less than $850K I would be very worried they are shipping product, anouncing that as revenue (with gross profit of 70%) but the product is not selling so no cash is being received. If anyone has other theories I am all ears!!
