subtract logged KR from your spark table(s).

It's only while on the 2-step from Lingenfelter. I just made both high/low timing tables identical, not sure if this is the correct way or not I just dont want to get out there next week and find it's still pulling timing.

is it a lot? (1* or more)
is it consistent?
this is when i subtract KR,
if it is under 1* and sporadic i just ignore it.
you can try subtracting 1/2 of the KR and see if it goes away.
make sure you are not getting because of lean fueling though.

It's 4 degrees, just while on the 2-step yet the decay keeps the retard for the entire run. If foot braking it does not do it.

Increase the values in B6207 knock retard recovery rate as well , try 80-90% increase, this will get the timeing back into it quicker.
