The difference is in the trajectory of the ball. HTO saw it being a high trajectory, meaning that it fell much quicker once it reached its apex, where as the Reds labeled it as a lower trajectory. HTO noted that hardly ever do the stadium guys pick the high trajectory, which is why we will at times see their numbers be off a bit from HTO.
