Yes...I think shifterboy has alluded to that.
If you have a knock event due to heat, then you have to reduce heat and the DME does this by pulling out some timing.
The next step should be to stabilize the unfavourable conditions (if they truly do exist).
If the combustion chamber was overheating, I would imagine that adding timing back in would just recreate the heat and result in another knock event in short order.
If however, your timing curve keeps rising after the knock event, then I get the impression this was just a DME induced adjustment for some reason other than knock.......at least that's what I like to believe.
I have also seen where the timing curve stays flat after the knock event.....neither rising nor dropping - so I am not sure what to make of this one.
