SMD Modelling with TRL

Very Basic question

I am trying to model some commercial SMD components over FR4 at around 2GHz with the classic 8510C. I was reading about the purity of the TRL calibration method and I am amazed with the results that are claimed.

So my question is , if someone performed this task before and can comment about the results. Also, is TRL more reliable than the mathematical post processing de-embedding of the fixtures?  I am just trying to figure out what would be the best method to use for this modelling.

Besides, some friend told me that he normally builds a electrically long line that wraps several time the Smith Chart to check after the calibration has been done.

Thanks everybody!!
