Question regarding reporting project experience for LEED CE credits

The USGBC's CMP guide says that "Work on a project registered for LEED certification will count for 1 CE hour per credit." There's not much explanation given beyond that, however. Does that mean that if the project is on track to get LEED Silver (i.e. 50-59 points/credits) you get that many CE hours for working on it? Do you only count the credits that your work directly contributed to and leave out things like Enhanced Commissioning, or other credits where you weren't the lead person responsible? Or does it mean that you get 1 CE hour for each LEED project you work on? This is my first time submitting CE hours for LEED since passing the test two years ago, so I appreciate any first-hand experience any of you have. Thanks!
