I also thought of SENSEI and since it’s a sound alike I was mulling over whether SENSEI is meant to be evocative of “census”, but hadn’t quite worked it out yet.
It’s not SENSEI, but a similar word. Only two letters are different.
SENPAI (PAI=Predictive Accuracy Index in crime statistics)
++++
The Voivode of Wallachia’s contemporaries called him paler than most others.(7)
Correct, but crime = sin, ratio = pi, sounds like “sin pi”
Impaler (sound alike)
+++++
To discuss again about the place where you live (9)
I’m thinking along the lines of “RESIDENCE”, but can’t see how “sidence” could mean “discuss”, so it seems wrong.
I think Oly’s playing off how RESIDENCE and RESIDENTS sound alike.
Not RESIDENTS/RESIDENCE, but correct first two letters.
Beware of misdirection RE puzzle type
An additional hint is hidden in the previous hint
So, something like REV+HOME+IEW? “review” ABOUT “the place you live”? Though obviously not exactly that, 'cause it doesn’t work.
Alternate wording:
To discuss again changing the destination of a letter (9)
Is it READDRESS?
Someone wisely tapped out a warning about the box. (8)
SOCRATES (SOS + crate)
Native’s kimono accommodates Alaskan. (6)
Native’s kimono accommodates Alaskan. (6)
