Default Having some knock readings, need advice.

Hello everyone, I am tuned on a COBB 91 octane shelf map, but can only use 90 octane because I live in Alaska and that is all we have. I decided it would be interesting to log in a morning run with the engine warmed up on my way to work. What I found was a little bit of feedback knock that I have never had in my countless other tests, does this look scary or should I not worry about it? Getting it tuned other than a third party tune is not an option for me as i am 300+ miles away from a tuner. No dyno in Alaska.

Lemme know what you guys think, thanks!
