Where's the proof that Itachi used a watered down version? The only thing I see in there that was less severe than a regular Tsukuyomi was the type of torture used.

As in, Itachi was using Tsukuyomi to wear him down mentally, but not incapacitate, which makes sense.

But there's no proof that it was weaker than a normal one. If the Tsukuyomi wasn't broken, Sasuke would have only experienced his eye getting plucked out. Not exactly the type of torture to put him down, so that means Itachi was leaving him able to fight but not necessarily expecting him to break out of it.

After all, he seemed pretty surprised when Sasuke did break out.

@Brainbrand, There's no indication against it either. In fact, it's more likely that Zetsu would notice if Itachi hit Sasuke with a Tsukuyomi that lasted more than a second. But instead, he just thought it was normal.
