Does hydration %age include levain? 1

Gurus, I have been happily baking a variety of breads recently.  My latest was 1,2,3… and it turned out beautifully. Does hydration %age include levain? 2 But it seems to me that with such a large %age of levain in the final dough, that the hydration should include the water in the levain, as should the total flour include the flour in the levain.  Is that wrong?

Thanks in advance.
