what's the practical meaning of "some really poor spots to split on"
The only drawback I've seen is that the epub are about between 10% and 20% bigger (this is because the compression algorithm used by epub is less efficient on many small file)...
epub is NOT a compression. An epub is just
a ZIP file renamed, that's all, nothing more. What makes an epub is what's inside the zip file making up the book.
As for splitting up the files. Yes you can get some pretty poor spots to split on. Since you are splitting the files inside by size rather than by chapters and the Kobo pagebreaks after every file, you will get pages of text that simply end with a lot of white space at the end but then have the text continue on on the next page. So you could end up with 2 sentences on one page and the rest of the text on the other.
