Marking the most recent claim of a property as preferred can be a nightmare when there are multiple claims for an statement. One example of this would be checking that the most recent ELO of a chess player is the preferred one in this example. In this example we have more than 100 different ELO each of them from a different point if time. Checking missing months or even finding the most recent one to set it as preferred is a PITA.
This also happens with the population of entities.
Sorting this claims by the value of the property P585 (point in time) would make things easier.
