My take on this as i've been through it, is most of what you have read about anything doesn't relate to any observations you will see.
Most of my changes have seemed counter intuiitive to anything i've read. YMMV

Steveo's Trimalyzer is now on version 1.3b
Have you viewed the knock counts in EEHack and in the analyzer view?

The LT1 doesn't have AE acceleration enrichment so any blip of the throtlle leans the motor until the PCM can figure out a new pulse width.
This is/can be burst knock which has it's own tables of retard.
You can get knock without counts increasing & increasing counts without knock.

OL runs with a lot less counts as i can run it richer. In CL i keep retarding timing and still get knock counts.
That image does look heavy though. So to cover some ideas, You have checked nothing is loose or catching underneath?
You have the right knock sensor for the PCM?

Also my current PCM has a fewer knock counts with an LT1 knock module than the previous PCM with an LT4 knock module, so don't get fixated by that notion either.

HTH some
