Three quotes, I believe. Quotes derived from the same source shouldn't be counted as multiple.
And two of these sources also state Yoda easily handled Dooku in other versions, lmfao.
There's also half a dozen quotes, all from unique sources, saying Yoda easily repelled Dooku's attacks, as I highlighed in my EU post.

There's absolutely no majority saying the fight was close. That's literally fake news. The majority of sources suggest Yoda won easily.
