There is a mistake in the final 4 rows of the chart. The SSK shown in rows 43 + 44 of the chart should be in rows 41 + 42. This is because the stitch count decreases from 9 stitches to 6 stitches, and then from 6 stitches to 3 stitches, which requires three decreases in those two rows of the chart. In the final two rows of the chart, the stitch count reduces from 3 to 2 stitches, then 2 to 1 stitch - whicm means the extra SSk is not required in those two rounds.
