What would be a desirable time period for publication between books?

I've devoted years to studying and learning but now I believe I'm ready to begin pushing out books. I finished 1.3 books in November. Plan on finishing the remaining 0.7 of the second book in December. I could actually publish 12 books a year but I thought having too many books might be bad for my reputation as an author, cause it might seem like my work is not original or carefully planned out.

It's also easier to half or quarter that and publish 3 books a year or 6 books a year, or even 1 book every 2 years. Also with 12 books a year, that would be 144 books in 12 years, which would mean my books would be harder to promote, since I would have to devote my book promotion time towards 144 different independent book creations. 288 books in 24 years and so on. Promoting 288 books might be harder than promoting 2 books.
