Weird Knocking on cylinder 2 and Knock retard

[RickyT]

So I've recently done a 3rd gear WOT log to play around with the flashpro for a bit and Ive notice my knock seem to be a bit high compare to the others logs ive seen floating around this forum. My knock starts at 150 in cylinder 2 and knock retard goes up as high as 15, after 4k rev or so it goes back down to 0/1, wondering what would be the cause of this. New to this so might sound a bit stupid just want to make sure my car is still fine... Ive attached the log here for you guys. Thanks alot
