A 45-minute consultation is a great way to

--address detailed questions
--learn modifications for an injury or other limitation/contraindication
--discuss any stuck points (mental barriers included!)
--or go through a portion of the class with extra attention to certain body parts

This shorter consultation / lesson is available for regular practitioners, whether newer to the practice or very seasoned and experienced.  Very new or brand new students are better served with a minimum of a 60-minute lesson.
