Practice makes Permanent, not Perfect
Airplane design engineer and SLF here so I will not comment on the specific foot position question directly. This discussion does however remind me of lessons learned on the football pitch as a lad. Coach drilled into us that "Practice makes Permanent" contrary to the old and incorrect adage that "Practice makes Perfect." The lesson was that you must practice proper form so that you are instinctively ready to use that when needed. If you practice incorrect form, you will perform incorrectly in the heat of the moment. I want the pilot whose plane my family and I ride in to treat every landing as a dress rehearsal for the one that goes bad and needs every bit of skill, preparation, and quick responses they have built up over the years.
Off my soap box for now.
