Paper DRF Trainer Category Performance Stats

[eqitec]

Does anyone know what the reporting time frames are for the trainer category performance statistics printed in the paper DRF under each horse's PPs?

E.g., 2YO, Turf, Routes, etc.

Thanks.

The link below from the DRF site says that the trainer stats cover the current year and the previous year.
