Delta/Yr below is a slope of the linear fitting over the data of the period. Delta/Yr/Yr is a slope of the liner fitting over the devivative data of the period. Slope listed on a linked plot is the slope computed on the last few periods of the data to show the direction of the trend, and different from that of Delta/Yr.
