The achievable precision of the cross section times branching ratio measurement from the event rates is estimated for the MSSM H/A decay in the associated production process gg 
at large tan in CMS. This work demonstrates that the above production and decay process exhibit a large sensitivity to tan and thus add as a significant observable to a global fit of the SUSY parameters. To illustrate this potential an example is given concerning the achievable 
determination accuracy that could be reached from the event rates and for a given set of SUSY parameters and uncertainties.
