Exclamation Is this real knock?

I have attached logs. I am encountering some random counts of knock.<br />just want to verify if they are real or phantom knocks
the 1-2-3-4 pull is the most interesting one.

It looks like real knock to me. Add more fuel - you are far too lean, and reduce timing in these cells.

Update:

you guys were right, it is real knock, well half of it.
weird that prior to posting i had tried pulling timing and knock count didnt change.
hence made me think it isn't real knock.
anyway, i fixed some lose stuff which were also causing rattles,
like there was a lose bolt holding an uicp bracket to the chassis, exhaust was leaning one side too much.
that brought the knock counts to a more reasonable level which i fixed by tuning the afrs and retarding timing.

thanks for the help guys, appreciate it
