At MWR this weekend, I was on field reset and repair. I did not see any "slack" in the overpass. It does sag a little bit - though I never got a tape on it to measure, but it is just as the rules and field description spell out. If you read the rules and check the tolerances in the field drawings that is what you'll get at the event. Although there are also several fields rotating between the events, other events might have different observations than mine from MWR.
The FTA's and field managers do a tremendous job to ensure the field set-up and conditions are accurate and maintained and keep them fair for the entire event.
