If I look at the individual points in Chandler's graph I posted above, I see both an increase and decrease between plotted points. Is Tony ignoring the fact that at some points the roofline SLOWED down compared to some of the previous plotted points? Is this why he and others insists on using the AVERAGE of those points in order to avoid the truth hidden in the graph?
The graph is of velocity against time, so a deceleration would show as a point being above the previous point. So far as I can see (show me an example if I'm wrong, please) each point is either at the same level or at a lower level than the previous point, so there is no actual deceleration, though the acceleration (given by how much each point is below the one before it) varies quite a bit, particularly at the beginning of the graph where Tony claimed the acceleration was constant.
