It also dropped your IAM down from to 1 to .88 but looks like it was quickly climbing back up. Your ECU should learn fairly quickly and retard timing in that RPM range to make sure the knock doesnt happen again.
And given the fact you just finished the break in period, I doubt you've had too many WOT pulls. Maybe do another log of a pull in a 1000 miles or so and see that knock is still present
