== Plan for roll-out ==
= Example (36edo) =
Edo pages which currently have  an "octave stretch", "related tunings", "zeta properties", etc. section:
* High priority pages: {{EDOs|7, 12, 17, 19, 22, 27, 31, 36, 41, 58 & 72 edos}}.
* Medium-high priority pages: {{EDOs|8, 13, 14, 16, 23, 99, 103, 118, & 152 edos}}.
* Low-medium priority pages: {{EDOs|32, 33, 39, 42, 45, 54, 59, 60 & 64 edos}}.
* Low priority pages: {{EDOs|111, 125, 145, 159, 166, 182, 198, 212, 243 & 247 edos}}.
 
; This standard will need to be rolled out to those above pages ''once this standard is ready''. (Not yet!!)
 
It can optionally be rolled out to more edo pages later.
 
; Things to note:
* When rolling it out try not to delete existing body text but instead rework it where possible.
* This section will ''not'' replace any "n-edo and octave stretch" pages. Still, add this section to the relevant edo page, but also link to the "n-edo and octave stretch" page at the top of this section, using the see also Template, eg: <nowiki>"{{See also|36edo and octave stretch}}"</nowiki>.

Stretching the octave of 36edo by a little over 3{{c}} results in improved primes 5, 11, and 13, but worse primes 2, 3, and 7. This approximates all harmonics up to 16 within 13.4{{c}}. The tuning 21edf does this.

Stretching the octave of 36edo by a little over 3{{c}} results in improved primes 5, 11, and 13, but worse primes 2, 3, and 7. This approximates all primes up to 11 within ''12.0{{c}}''. The tuning 21edf does this.

If one intends to use both 36edo's vals for 5/1 at once, stretching the octave of 36edo by about 1{{c}} optimises 36edo for that dual-5 usage, while also making slight improvements to primes 3, 7, 11, and 13. This approximates all harmonics up to 16 within 16.6{{c}}. Several almost-identical tunings do this: 57edt, [[93ed6]], [[101ed7]], [[zpi|155zpi]], and the 2.3.7.13-subgroup [[TE]] and [[WE]] tunings of 36et.

It can optionally be rolled out to other edo pages later.

* When rolling it out try not to delete existing body text but instead rework it where possible.
* This section will ''not'' replace any "n-edo and octave stretch" pages. Still, add this section to the relevant edo page, but also link to the "n-edo and octave stretch" page at the top of this section, using the see also Template, eg: <nowiki>"{{See also|36edo and octave stretch}}"</nowiki>.
=== What to do with edonoi pages that are very close to these edos ===
* Edt and edf pages should be permanently kept
* Other edonoi pages should be temporarily kept until all [[XW:NG|notable]] information from their respective pages has been added to:
** The "octave stretch and compression" section of the edo page.
AND/OR
** A new "''N''edo and octave stretch" page (create one of these if there is too much information to squeeze into the "octave stretch and compression" section).
=== Possible tunings to be used on each page ===
You can remove some of these or add more that aren't listed here; this section is pretty much just brainstorming.
(Used https://x31eq.com/temper-pyscript/net.html, used WE instead of TE cause it kept defaulting to WE and I kept not remembering to switch it)
