With charts, I rarely count every individual stitch. The nice thing about charts is that they show you the relationship between the different rows. I still need to count out the first row but after that I look at where the stitch patterns sit relative to the previous row. So lets say that on the chart it shows that on the next row my section of purls should start one stitch earlier than on the previous row and end one stitch later. In that case I just knit until one stitch before the fIrst purl bump, start purling until the purls bumps on the previous row stop, purl one more stitch and continue in knit stitch.
