no, it needs some experience or trial and error.
It maybe easier to choose a rowsep of 20pt and then adding
the extra space.

put it into a table and choose a p column for the brace text





\begin{tabular}{p{2cm} c}
      [name=X1] & \\[-25pt]
                & \dianode{S}{Condition1?}\\[0pt]
                & \rnode{SA}{\psframebox{do something}}\\[-25pt]
      [name=X2] & \\[0pt]
                & \dianode{R}{Condition2?}\\[-10pt]
      [name=Y2] &
      \psbrace[ref=r,rot=180,nodesepA=-8pt](X1)(X2){Stage 1}
      \psbrace[ref=r,rot=180,nodesepA=-8pt](X2)(Y2){\parbox{2cm}{Stage 2 
        looooooong text}}
