@s_kala,
Here is a summary of that KB article.
Fundamental difference:
A/B Activity without auto-allocate: Winner is determined by comparing the control experience to all other experience. IE: In a scenario where you have three Experiences: A, B, C without auto allocate the following comparisons will be made: A vs B & A vs C.
Activity with auto-allocate: Winner is determined by comparing every experience with every other experience. IE: In a scenario where you have three Experiences: A, B, C with auto allocate the following comparisons will be made: A vs B & A vs C & B vs C.
Advantage:
Auto-Allocate performs all implicit comparisons across experiences and produces a "true" winner. There is no notion of a "control" experience in the test.
Disadvantage:
Doesn't support A4T (Analytics for Target)
Hope this helps!
