If a person were to completely throw out the photographic time evidence, it is still possible to ascertain the order that teams completed the climbing task at the condo towers. Careful examination of the photos show the location of the counterweight/counterbalance bags that assisted the racers as they climbed. Before any teams arrived, there are 6 bags tied off at the top of the tower, one to each climbing line. When Rachel/Dave were climbing, only their set of bags were going down. When Brendon/Rachel were climbing.........the R/D bags were at the lowest point and B/R bags were descending and the Art/JJ bags were still at the top. When Art/JJ were climbing, 4 bags were tied off at the lowest point and only one set of bags were descending. I hope this makes sense.
One photographer took pictures of Brendon/Rachel on the descent. He did not take pictures of Rachel/Dave or Art/JJ.....but there were two sets of descending rigs at opposite ends of the building.......as seen in the photographs and he could not physically take picstures of R/D and probably of Art/JJ is they used the same rig as R/D.
