So I am trying to understand what it changes in the epub file, I tried it on a drm free project gutenberg file, also tried it on a standard ebooks file, does standard ebooks already have Metaguiding feature in them?

both are the public domain type of epub files, I noticed that google play books likes its epub 3 format better than the normal one if you upload an epub 3 with metaguiding to it, seems to process it better/

I noticed in the project gutenberg the font size and spacing seems a little different, also I am unsure how to convert these metaguiding epub to say kfx format for kindle paperwhite ereader using calibre and kindle previewer 3 software with kfx output plugin and if it will keep the changes to them or use azw3 with transferring USB method? I just don't recall it being called that it might of been.

if megaguiding epub works if you use Send to kindle app in windows or their website, there you can send an megaguided epub directly to the docs in your cloud library, which it takes longer to process them on amazon.com website it seems.

ok, on a standard ebook it seems to make the font darker and sharper but the spacing of the text seems almost the same, for example the first two lines are the almost the same seems to start changing on the second line of text with the spacing of words, is that all megaguiding does for it?

I never heard of the term metaguiding before now, but teachers did use to use color paper in school to help us read stuff per lines, sometimes because of that special ed classes they did try stuff like covering each line like back in middle school I think. but I don't recall it being called metaguiding at that time, its been more than a few years since then but it was not used in DESP classes in college.
