It seems that to keep the decreases symmetrical, you’d end with the p2 (since the RS ends with a k2).
Have you tried working a few rows to get a sense of the decreases in a kind of overall effect? Sometimes the result is different that just looking at a row or two.
Yes; In fact I frogged 14 rows of the p2, thinking it was too wide. Then I did 6 rows of p1 and it looked too narrow! Of course, i was comparing it to the left side that I have already blocked. Would that make THAT big of a difference?
