The achievable precision of the cross section times branching ratio measurement from the event rates is estimated for the MSSM H/A -> tau tau decay in the associated production process gg -> b bbar H/A at large tan beta in CMS. This work demonstrates that the above production and decay process exhibit a large sensitivity to tan beta 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 tan beta determination accuracy that could be reached from the event rates and for a given set of SUSY parameters and uncertainties.
