if [Harry] asked [Hermione] the right questions under veritaserum he could probably find out about the huge chunk of missing time she has in her memory
What huge chunk of time is missing from her memory?
The only moments she misses are (according to Harry’s theory)
the moment in which she remembers seeing Draco and Snape plotting against her, which was implanted by a FMC and removed after the duel (leaving all the true but misleading memories of being furious at Draco in place)
and a short time intervall after the duel, where the false memories of her performing the Blood Cooling charm were inserted.
In addition, we can assume that these memory charms were very precisely executed because of their utmost importance to the plan. Thus, even the transitions between these false memories and the true memories surrounding them would probably be unnoticable. (Remember, a legilimency expert already checked her.)
(Of course, there is also the Groundhog Day incident when she really lost a huge chunk of time – but it’s not related to this event in any way that’s obvious to Harry. I’m not aware of any evidence that he even knows about that.)
I was referring to the Groundhog Day incident. Harry probably isn’t aware of it, but could come across it by asking simple questions of Hermione like “why were you so angry that day of the battle?”. Hermione seems aware that she is missing memories here, due to her “lost track of time” statement to Susan.
Thinking of what Draco might have done to her and then obliviated seems a reasonable explanation for her anger towards him during the battle, and perhaps why she can believe that she did attempt to murder him.
