Hi Clotilde @[CSatt.1] ,
you are right, there is some little variation across the documents.
However, please note that if you need the exact ODR speed for performing calculations, for example for synchronizing acquisitions or using raw data to integrate velocities or displacements, you cannot rely only on the online documentation.
In fact, on datasheets and application notes the typical values are defined, and if there is discrepancy among them, the datasheet declared value must be preferred. Moreover, and most important, the true ODR can vary also of some percentage points from the nominal value (1%/2&), and must be measured case by case, for example exploiting the DRDY (data-ready) interrupt and measuring the rate.
