Default Weird negative timing on deceleration / engine braking

Sup guys...

A few basics about the car -- 2002 wrx, full stage II junk (full TBE), drop in filter, stock IC, stock turbo, stock tranny. 91 octane.

This comes from a custom stage II tune with very conservative timing (basically the same as stock, just smoother). The load sites in question with the negative timing correspond to ~26 degrees of timing on the map. Should I worry about this? There is virtually no load being placed on the engine, and I would guess that it is either the hyper sensitive knock sensor, or drivetrain noise, etc...

Anyone else seen something like this?
