Post by JohnRichard,
It's been awhile since I analyzed the requirements of the Status field.
However, I do recall, that the status of a summary line tracks the
calculated status of the subtasks. In other words, if one or more
subtasks is late, then the summary shows late, unless one of those
subtasks is a milestone (0 duration). The calculated status of each
subtask is determined by the status date and the cumulative percent
complete. And yes, it can be kind of confusing.
Maybe it would help if I could take a look at your file, or at least a
representative sample that shows the issue. If you're game, zip the file
and send it to me at the address below. I will ask a few questions.

Post by JohnRIchard,
I played around with the Status field for summary lines and came up with
something that I think will shed some light on how Project determines if
the summary is late or not.
Add Actual Duration field and a spare text field as columns in a task
view (e.g. Gantt Chart or Task Usage). Customize the spare text field
with the following formula.
Text1= projdatediff([Start],[Status Date])/480-1
In the Customize fields window, select the option to use the formula for
calculating task summary rows.
Compare the value in the customized text1 field with the value displayed
in the Actual Duration field. If the custom field value is equal to or
greater than the Actual Duration, the summary line will show "On
schedule". If the calculated field is less, the summary line will show
"Late".
How does it work? Well, the formula calculates the expected progress the
day before the status date (i.e. cumulative percent complete by the end
of the day before the status date). It should be easier to understand
than deciphering the timescaled data.
Hope this helps.
