On Chart B, if you place markers around the repeats, you will have to move the markers around, because the number of stitches to the “right” and “left” of the markers is not always correct for the stitches that need to be worked:
On row 55, the stitches for the SSK immediately to the left of the repeat red line sit to the left and right of the marker.
Once you pick which side of the cable to place the marker on, you’re going to have to move it every 2-4 rows due to where the increases are happening.
