Graph description: Difference inaccuracy scores against average of the two scores

This is a scatter diagram, showing a triangular cloud of points. The horizontal scale shows the average of the Accuracy score for A and B, labelled 70, 80, 90, 100, 110. The vertical scale shows the difference in Accuracy score, A minus B. labelled minus 60, minus 40, minus 20, 0, and 20. The triangular cloud of points has the three vertices at about average = 75, difference = minus 50, at average = 90, difference = 20, and at average = 108, difference = zero. The vertex at average = 75, difference = minus 50 is an outlier. The points are marked as diamonds for A first and as squares for B first, but there is no obvious difference in the pattern.
