The math is simple: 'Target/Complete'. According to your logic, a
target date of 3/31/11 with a complete date of 5/31/13 scores 'Good'
(returns 0.980881). Don't you think completing a project 26 months
behind target is a bit rediculous? I think you want to re-examine how
your grade scale works. Maybe use the number of days and prorate that
to a predefined table such as would be used for student grades.
