100 a day is very rare. Industry statistics for the average practitioner is between 10 to 20 a week.A friend of mine is in the field, he sees 100 patients a day.
Don't forget income is before expenses such as rent supplies memberships etc etc. do the maths it starts to get rather un impressive as a career.
Over 80 percent of practitioners fall into this bracket. The only ones still promoting this as a viable career path is the colleges.
