Average spend calculates the collection done on average per guests unique visit.
Example - If 10 guests came to a salon spread across multiple dates and spend $15000, Average spend would be 15000/10 = $1500. If a guest came to the business twice within a time period but on different dates, the guest gets counted once per day
