It appears your question is: "If my task is on schedule, what should be my
%Complete on a specific status date?"
A formula can be applied to calculate the %Complete where you should be as
of the status date. The formula must address times when [Status] is (1) Prior
to [Start], (2)during the duration of a task, and, (3) after [Finish]. The
following formula can be applied to a spare column such as [Text1]:
str(IIf([Status Date]<[Start],"0",IIf([Status
Date]>[Finish],"1",ProjDateDiff([Start],[Status Date])/[Duration]))*100)+"%"
The formula can be used to compare with the %Complete field which is also a
duration based calculation.
