I thought I tried that, but apparently not the exact right scenario. Based on your suggestion, I think I have a working example now.
Here’s what I did. Tasks 1-4. Task 1 -2 are linked. Tasks 3-4 are linked. Task 1 assigned to resource A duration 3 days. Task 3 assigned to resource B duration 2 days. Tasks 2 and 4 assigned to resource C with 3 day duration each. So before leveling I have two small independent waterfalls. Task 2 starts 1 day later than Task 4, both assigned to resource C.
When I leveled, Task 2 was delayed because Task 4 had an earlier start date.
My mistake when I tried this originally was I had all 4 tasks in a common predecessor chain. When I break it into two independent chains, I can see the Date tie breaker delaying one task with a later start date.
Bottom line, it delays the task with the later start date.
Thanks! Sometimes you just need someone not in the forest to make a suggestion.
