# Summary

Proposes a more precise version of Cost Plus calculation, intended for use in assigning transfer prices for inner source work. Does so by grouping git commits by the amount of time between commits (< 360 minute time difference, 360-720 minute, 720-2160 minute, and > 2160 minutes or no related commits) and assigning time worked with formulas for each group, taking into account realistic assumptions, validated inside a large organization using inner source.
