1. A method of measuring performance of a vehicle, the method comprising:
applying a pre-defined model to the operation of the vehicle;
collecting operational data from the vehicle;
generating a performance measurement from the operational data;
determining a gain based on the performance measurement;
archiving the operational data if the gain meets a threshold;
expiring the operational data if the gain does not meet a threshold; and
training the pre-defined model with the archived operational data.
