Despite its rarity and richness, this group of data has one major disadvantage : its date isn’t precise. Some statistical methods allows us to manage properly these imprecise dating intervals. We have tested four different methods : determination of midpoints, use of lowers and uppers interval boundaries, and then the method which consists on examining for each year the probability of occurrence of each land transaction. If all of these methods allow us to visualize the same trend, they can’t lead us to understand rythms with the same level of subtlety, and are not always appropriate. We demonstrate here that the probability of occurrence method is the most relevant. Thanks to this method, we show how a huge number of lands regrouping take place after the One Hundred Years War, few years before the recovery of partition into lots, and that the rhythm of these ones isn’t similar between the center and the outskirts of the city.
