Formulas missing in Profiler user guide

i found that in the previous version of profiler user guide, formula for the metrics are provided.
For example,
Metric Name: branch_efficiency
Description: Ratio of non-divergent branches to total branches
Formula: 100 * (branch - divergent_branch) / branch

But in the latest version, this “formula” part is replaced by “Scope”.
Do anyone know where can i find those formulas for latest profiler. Since nvprof add more features and metrics, i am not sure if i can still use the old version formula provided by nvprof v5.0 or previous.
