Does the wind calculator in BC Calc® use Main Wind Force Resisting System (MWFRS) or Components and Cladding (C&C)?

BC Calc® tall wall wind load calculatoion is based on Components and Cladding (C&C) loads following the analytical method for low rise buildings in ASCE7, and we use zone 4 interior pressures.  Topography factor is assumed as 1.0.  If anything outside those assumptions is desired, you can calculate and input a wind load directly and the program uses it as input without modification.
