At the very least, the dictionary obliviation attack is pretty clever. In retrospect, it’s kind of obvious—but no one else in canon or MoR does it. (Harry could think of it easily based on his experiences with his occlumancy instructor, but hasn’t yet, probably because it’s a very Dark technique or because he can’t yet obliviate.)
It is clever, although if he has to make enough attempts in a row, Hermione may notice the missing chunk of time. That wouldn’t be enough info in itself to reveal what’s been going on, but it should make her suspect something malicious, and possibly even that she’s had her memories tampered with.
Time-Turners are locked onto a single person’s use and cannot normally be used to transport more than one person back in time (Harry and Quirrell had to go through some trouble to travel back in time together using a single time turner, although now I am wondering why they didn’t just use simultaneous rotations to meet with each other in the past; surely Quirrell has his own time turner?)
Time-Turners are not normally locked like Harry’s is (which also has the restriction on the time of day when it can be used). For instance, in Prisoner of Azkaban, Hermione uses her Time-Turner to transport her, Harry, and Ron back in time simultaneously.
If Quirrell had his own Time-Turner, then they could have avoided using Millicent’s, unless Quirrell wanted to keep his possession secret from Harry. In any case, using two Time-Turners is silly, because that uses up the 6-hours-per-day limit of both Time-Turners instead of just one.

Then how did Quirrell figure out the restrictions on Harry’s Time Turner without so much as laying eyes on it? All he should have known from Harry’s temporal discrepancies was that the thing existed. That implies to me that the set of locks Quirrell mentioned are a standard operating procedure, and the only extras that Harry’s turner has is the protective shell / locked before 9 PM combo.

The snake twitched its head, a snakish nod. “Many resstrictionss. Locked to your usse only, cannot be sstolen. Cannot transsport other humanss. But ssnake carried in pouch, I ssuspect will go with. Think posssible to hold hourglasss motionlesss within sshell, without dissturbing wardss, while you turn sshell around it. We will tesst in sseven dayss. Will not sspeak of planss beyond thiss. You ssay nothing, to no one. Give no ssign of expectancy, none. Undersstand?”
Nevertheless, it seems possible that if Mr. Hat-and-Cloak has a Time-Turner, he would be able to break the wards on it (Quirrell only avoided doing so because it would be noticed upon inspection of Harry’s Time-Turner, and Mr. Hat-and-Cloak is not likely to have that problem).
Very true; I’ve forgotten whether wizards can create false memories to cover up big time gaps. If they can, it’s a much smaller problem than it looks.
But we have reason to believe that Cloak-and-hat was not expecting to have to make very many attempts, that he either is usually very good at the dictionary attack or he’s that Dunning-Kruger—he got so frustrated he exploded and asked a revealing question outright. And then, the writing seems to imply, he only needed one more try to crack Hermione’s code.
So, this reads to me like an expert using an effective tool who happened to run into an extremely unusual girl/problem, not a only-modestly-clever-or-perhaps-even-stupid person. (Also, thinking again on my remark that it’s a very Dark technique, I’m even more confident that this is not Lupus or Sirius—neither of them seems like the kind of character to pull such a Slytherin technique.)

This will not happen if Hat-and-Cloak has access to a Time-Turner.

Pedantic technicality: not Ron.

It’s never Lupus.
I walked right into that one.
