How to get the same line amount on facing pages
Dear Forum Readers,
I just saw two books which both are 200+ pages.
Two novels to be exact.
What cached my eye is that both novels had all their facing pages the same amount of lines.
I mean: all except the first and last pages of each chapter.
This is a photo from a "regular" novel typesetting. (I blur the lines because of copyright)

The teal mark shows the one line difference.
And here is an example of the "same line amount on facing pages". (Most facing pages had 29 lines. A few had less or more)

Can someone tell me how to make each facing pages to have the same amount of lines?
That's not a problem if not all pages has the same amount of lines. That is fine. I care about the facing pages.
Of course one can do it manualy. But does anyone has an idea how to do it by using paragraph styles, layout settings, baseline grid magic, heretic mathematical equations or whatever solution which can do this with hundreds of pages?
I would apriciate an answer.
If there are more ways to do it, I'm all in to hear about them.
Best,
