target:  Calculates the "best-in-class year" of the device. This represents the top-end or flagship devices of that year, not the actual release year of the phone. For example, the Galaxy Duos S was released in 2012, but its specs are very similar to the Galaxy S that was released in 2010 as a then top-of-the-line phone, so it is a 2010 device.
