What does knock look like on the 1.6 oil gauge?

What does knock look like on the 1.6 oil gauge?
I remember it being described as violent back and forth twitching.
I'm asking because I have no knock sensor and I've seen it wiggle a little at about 10in vacuum and 3000rpm, as it's passing from 50-60psi. I doubt there is knock, I think my gauge is just a little sticky. As far as I know my engine has never detonated since the turbo went on.
Who has seen detonation through the oil pressure gauge?
More importantly, has anyone had detonation and didn't see it in the oil pressure gauge?

The 90-94 oil pressure sensors are carbon resistance sensors. As the carbon is compressed, the resistance changes. Detonation shock waves travel through the carbon sensors with massive changes in resistance that is indicated by the gauge needle flickering wildly to the left.

Ahh no ****, I didn't know that. Interesting.
I do know that crusing the highway my oil pressure bounces around my 1.8 (with 94 sensor). I figured the sensor was bad and was going to change it with a spare. Maybe it's knock! hahaha.
