1. About % complete and % work complete

% complete = completed part of task's working duration expressed in percents

% work complete = completed part of total work (man hours) of the resource-task assignment expressed in percents - this is a more accurate tracking method

Those two definitions shows that the % work complete value may differ from % complete value if the work isn't evenly distributed in time (e.g. if a resource have one or more days off while working on a task).
