Water / Red Tea

I have a question about drinking enough water.

I understand that coffee/tea/soup, etc. do not calculate into the "water count" for the day.

However, Kathleen does recommend herbal teas (as I recently read in SARP), so I am assuming that means that herbal tea
would count towards our daily quota of water.
Do I understand correctly?

My specific question is about red tea.
It has no caffeine.
If I drank 6 cups of water and 2 cups of red tea, would that count as 8 cups for the day?

Thanks for your insights :h11)
