We use all relevant data, such as error statistic, number of bytes written and read, number of mounts, and age of cartridge to calculate VeriScore.

The parameters are weighted according to their importance on the cartridge quality. Error counts are weighted more heavily than age of the cartridge, for example. Some types of errors, such as recovered write errors, are weighted more heavily than others and are less severe than a non-recovered read error. More recent errors are more important than older errors.
