What are the SimBrief takeoff and landing performance data based on?

Can you please speak to what the SimBrief takeoff and landing performance data are based on and what your perception is of its accuracy relative to built in performance calculators for products like the PMDG 737s and Fenix A320 family, please? They can sometimes give drastically different outputs and I’m not sure who to trust. It seems like SB possibly takes more variables into account, but unsure if that’s true.
