Its hard to read on my PC but it appears just about all of those areas are at partial throttle cruise. Knock correction is a table and without seeing the learned knock correction table where the ECU as actually adjusted advance Its hard to say.... I can view that with the Flash tool but not with Delta dash.

The idea that the second knock correction happens, the result would be a reduced IAM is just not correct. There are many other factors that determin the IAM and time is one of them. You wont see reduction if you reset and do some pulls.. I have had cars come in with "machine Gun detonation" do due a mistune or a parts change that effected the tune.. I am talking audible "clack, clack, tick, clack clak" along with unburnt fuel smoke out the tailpipe bad knock... and the IAM will be at 16 through all of that.. From those logs I am not seeing a car that is knocking badly.. Hard to say and hard to read.
