Knock Sensor spark?

KNK_SEN_RETARD is what it's called, or what I'm talking about.
When the number is positive it it adding spark, advancing, or retarding spark?
I assume it's adding spark but I just want to be sure.

Also, should I let the knock sensor do it's thing or should, can, I adjust the timing at those loads to keep the sensor from adding or removing timing ... much the same process as doing the MTF?
Something like you'd only want to see the KS add/subtract 0.5* at most instead of the -5 to +6 I'm seeing now.
Steady throttle, 60mph, on my way home I logged and all the KS did was add timing, positive numbers, moderate loads, 0.65 and below ... but load for me right now is all screwed up I think, WOT nears 1.9 for a load vs the 1 I think it should be; figure that out when I can, if I can.

Don't "think outside the box".
There is no box.
Do it correct, or do it twice.
