Lifting my chin off the cue

Been for a practice tonight, about 1 hour in I'm playing absolutely ****e.

So for some unknown reason I deliberately lifted my head when down on the shot so there was about an inch or so between my chin and my cue. All of a sudden I could pick out angles, had better control of the cue ball and they were going in off the lampshades.

I'm sure this isn't advisable from a technical point of view but has anyone else ever tried this?
