I found a way of tracing out of sequence logic using the predecessor tab on the detail window using the "GoTo" button.
Bascially you have to turn on the Start and Finish and Early Start and Early Finish date columns in the tab.
Then evaluate the data. Sorting by early finish can help when you have allot of tasks.
The tab looks like the attached image.
Note that when a task that is completed has no predecessors that are not complete, the Early Start and Finish reflect the data date of Feb. 11.
For the tasks that are compelte that have a predecessor that is not complete, the Early dates reflect that incomplete predecessors calculated dates.
