I just discovered a setting for "worksharing update frequency" What is this for?

Could it be the solution to my design option save/relinquish vicious cycle? (see my design option workflow thread below) When two users are working on the same design option, they get nonstop demands to save-to-central and relinquish. Would this slow down the demands? What does the manual setting accomplish?

F1 Help wasn't very helpful on this topic.
