Wasn't covered at-all on my CRI course,
No, I don't think it was.
However, back on theme (we can argue about the CRI Course later!)...
In Ireland I teach to some extreme attitudes.... and was shocked when one of my students told me (after test) that I was a pussycat in comparison to the examiner who gave the student some harsh attitudes that I didn't dare push the aircraft to.
Recovery is always the same - power to idle, check ASI for caution range, roll then pitch. In these instances I am happy for the student to recover to a straight and level attitude and never had an examiner want anything other than that.
