His test results however, were declared invalid by Savage and Hyneman, because they determined that Adrian was so used to swimming in water, that his technique was completely disrupted when swimming in the syrup. This disruption caused his lap times when swimming in syrup to vary wildly in comparison with his extremely consistent lap times in water.
