Average spend
Average spend calculates the collection done on average per guest's unique visit.
Example
If 10 guests came to a salon spread across multiple dates and spent $15000, the Average spend would be 15000/10 = $1500. If a guest comes to the business twice within a period but on different dates, the guest gets counted once per day.
[Sale Value is divided by Guest visits]
A = Get value running Collection metric
B = Get value running Guest visit
Avg. Spend = A divided by B
