There is no such thing as KR programmed by the PCM to reduce torque on shifts. The PCM retards timing independent of the knock detection system.
KR is a direct result of noise picked up by the knock sensors in a certain frequency range. There is only knock, and false knock... there is no "programmed knock" for torque management.
You don't have to agree with me, you can just be wrong.
The small blips that Chris is seeing (under 1*) are likely from noise being picked up somewhere else... not from actual knock/detonation.
The characteristics of real knock are opposite that of false knock.
