I agree with that. If one result happens to be 1% faster and the next one
is 1% slower, they differ by 2%. We need to take data points around them to
draw a conclusion. But the data point is at very end of the graph which we
do not have enough points around it, so I think it is risky to get any
conclusion from it.
