Kyle Kilmartin,
It looks like you've got it right but it's a little hard to tell since the tasks in the upper part are off to the left of the view. You also may want to turn off showing the critical path or perhaps change the color of the mock progress lines for easier visual reading.
For reference, this is the test file I created for developing and testing the workaround. Ordinarily I would not display the "real" progress lines along with the mock progress lines as it makes it harder to see the mock progress lines but it does provide a visual comparison. Note, the two summary line mock progress lines are quite hard to see due to the thin line style I chose.

This is what it looks like in Print Preview, which of course is the reason for the workaround.
