True, but it's still a factor: on my laptop I get

--8<---------------cut here---------------start------------->8---
previous-line  2           1.435139      0.7175695
next-line      1           0.446293      0.446293
--8<---------------cut here---------------end--------------->8---

being very careful to avoid next-line/previous-line in any other
context:  that was one next-line from "Other" to "Closed issues" and two
previous-lines from "Closed Issues" to "Other" to "Development
Tasks". Given the five previous-lines in your profile, I suspect that
one or two were much longer than the others which skewed the average.

Given the evidence that Lawrence Mitchell provided however, it seems clear
that most of the blame can be placed on overlays - no?
