Knock Level / Fuel Cut

I always see a high knock level when decelerating and the fuel is cut.

Here is an example, the knock level is around 20 and when decelerating the knock level peeks to 72. I wonder if this is just engine noise or really knocking. Maybe the last cycle before the fuel is cut is to lean?

Most likey drivetrain noise as it can not be true knock. Think about that a little.
