You've made progress! You're doing short row shaping, now. Your best bet is just to do exactly as the pattern says.
If it says to knit to the last two and turn, do it.
On the next row, when it says to knit to the last four, knit to the last four. Take each row at face value.
Looking at the rest of it, each time you knit a set of rows, you're knitting only the middle stitches, and making this center row shorter by two stitches at each end. This will make the middle of the piece longer than the ends--thus the short row shaping.
"Trust the pattern!"
Time flies like an arrow, but fruit flies like a banana.
Hop aboard while we follow the cloud-covered van of knitting harmony, man!! Woooo!! --Hedgehog
