Rds_on, LT Spice model vs datasheet, for C2M0045170P

Hello, I have observed that when I exercise the Wolfspeed LT Spice model for the 1700V SiC discrete module C2M0045170P, I don't seem to be getting the same result for Rds_on as is shown on the component datasheet.

The datasheet states that for Ids=50A, Vgs=20V, and Tj=25C, Rds_on should be 45mOhm. In my simulation, I'm getting 35.5mOhm.

I'm trying to account for this small discrepancy between the datasheet value for Rds_on, versus what I'm getting from my simple LT spice simulation. Any insight would be appreciated! Thanks.
