$\frac{\sum _{c \in g} \mathit{RewP}(c)}{\mathit{C}(g)}$

$\mathit{RewP}(c)$ returns the rework percentage for case $c$ .
$\mathit{C}(g)$ returns the number of cases in group $g$ .

$\frac{\sum _{c \in g} \mathit{RewP}(c)}{\mathit{C}(g)}$

This indicator is implemented in the process_performance_indicators Python library.
