Troubleshooting Knock Correction Advance

[Brando]

RomRaider logging/graphs:

I'm working through tracking down knock correction advance. I have checked and made sure nothing is loose and rattling against the motor.
If I decelerate or keep a constant throttle there is no knock correction advance. When I accelerate hard I get knock correction advance of 9* in first, 7* in second, 5* in third.
The knock correction seems to run in sync with the amount of throttle + load on the motor.
If I am in neutral and blip the throttle I will get a 4* correction advance but it's just a spike and if i hold the throttle it goes away.
If i ease into the throttle there is little to no knock correction advance.
My graph for Feedback Knock Correction stays flat-lined while the knock correction advance is spiking, so that would mean the correction isn't due to an actual knock, is that right?
I'm still learning about all this crazyness, but doesn't that mean something else like the MAP is responsible for the knock correction numbers?

I have a data log if it helps
