I've learned a lot over this last season so many many thanks to you guys that know, and for putting up with me, that doesn't

Any help understanding spark knock would be greatly appreciated and to this end I've attached a very short snippet of a log (Power Vision) which captured a couple of events.

For starters I suppose, I've read about false knock events and wonder what you think of these??

And, naturally, what might you do about these examples, as an example?

cheers guys
