SLS PE3

I presume a lot of work still needs to be done to increase the depth of the squat

Hey Hermann, for the long-term health of the knee I suggest you to strongly arch the inner part of the feet and feel the weight on the outside edge / heel of the feet. for your IM try to do the exercise more slow and also focus on complete the rotation of the upper leg so that the working leg reaches the position in the photo below (basically you tend to drop it too early).

Thank you very much, Alessandro. I will try to practice both pieces of advice.
