As you can see in the chart above, the patent describes a secondary validation stage to which a serial number and the "user identification information" are checked against "reliable data, such as that sourced from the manufacturer or developer of the media title."
This information could include account names, location, IP addresses, the speed of the user's connection and product license numbers.
The secondary validation would account for load time errors caused by hardware issues, but would also be skipped entirely if the first cycle - the load time benchmark comparisons - checks out.
