The first time I put my elbow down it felt sketchy and I wasn't sure if I would be able to repeat it. I have been practicing in the same lot and trying to develop physical reports for myself to make it repeatable and more importantly, consistent and predictable. I am still not totally there yet, but this recorded session was a huge step in the right direction. By the end of this practice session I was able to decisively put my elbow down when and how I wanted, albeit still exaggerating a lot of the BP (which may be necessary at parking lot speeds). General lean angle (per the BMW) was 52 - 54 degrees, both sides.
