@ezekgabrielse It groups commits together within an hour range and assigns hours based on those groups. So if you commit a 9:30, 10:15 and again at 11 it assumes you worked for 1.5 hours straight. If you commit once during the day it assumes you worked 1 hour. It's a good fit for those who use their git history to track what was done each day and to use it as a way to judge how long you worked on a feature on a given day. It's a passive way to estimate hours logs.
