Your account shows the hours you have been credited, season by season.
Where the number comes from
Hours are credited when a shift you worked is completed — usually from the times you checked in and out at the tent, or from the shift's scheduled length if the organization does not check people out.
A coordinator can also add or adjust hours by hand, for work that never was a shift: the afternoon you spent building the stage, the drive to the airport. Every entry says where it came from and who added it.
Nothing is ever quietly rewritten. An adjustment is a new line, not an edit of an old one, so the history stays honest in both directions.
Goals
Some organizations set an hours goal — the amount of volunteering that earns a pass, a shirt, or next year's invitation. If yours does, your page shows how far along you are.
A goal can be set for everybody, for a crew, or for you personally, and the one that applies to you is the most specific one that exists. You are only ever measured against one number.
Something is missing or wrong
It happens: a tablet missed a scan, a shift was recorded against the wrong person, somebody forgot to check you out and the shift closed at its scheduled end rather than the two extra hours you actually stayed.
Tell the coordinator for your crew. They can correct it directly. You cannot edit your own hours, for reasons that should be obvious to everybody except whoever is asking.
