I've had the same spot, running 94 octane in canada, now i don't have my BPB installed yet so i don't if that's anything but our gas has a bad reputation.
I might just switch to the 91 rom just cause our gas sucks and i cant get 94 everywhere i might end up.
Running A01C 93octage Stage 2 UEL
This log has 4 3rd gear pulls each had the same area of knock,
