Default DataLog - Fine Knock Learn (negative)

So, I logged today my stock 2012 SWP WRX with Stage 1 / 93 octane map and I found that in 3rd gear between 3790 and 3906 RPM I have some negative fine knock learning...thus, the car is pulling timing. Is this normal, I read some threads but most seemed to be modded cars.

Anything to worry about or is this nothing to worry about.

Thanks!

You'll always get some occasional correction. What you are seeing here is not a big deal (and it has already started learning back to zero). You want to put the car under some load and see what the knock situation is there. Check out our data logging video:
