I want to use the solution explained here:
How to calculate an average profit per day with Google Sheets
But in just a single cell instead of having to use 4 different cells for the calculation.
I came up with this formula but it seems to me too complicated and inefficient:
=AVERAGEIF((arrayformula(if((arrayformula(if(query({A2:A, arrayformula(int(A2:A))}, "select max(Col1) where Col1 is not null group by Col2 label max(Col1) ''", 0)<>"", vlookup(query({A2:A, arrayformula(int(A2:A))}, "select max(Col1) where Col1 is not null group by Col2 label max(Col1) ''", 0), {A2:A,C2:C}, 2, false), "")))<>"", (arrayformula(if(query({A2:A, arrayformula(int(A2:A))}, "select max(Col1) where Col1 is not null group by Col2 label max(Col1) ''", 0)<>"", vlookup(query({A2:A, arrayformula(int(A2:A))}, "select max(Col1) where Col1 is not null group by Col2 label max(Col1) ''", 0), {A2:A,C2:C}, 2, false), "")))-QUERY((arrayformula(if(query({A2:A, arrayformula(int(A2:A))}, "select max(Col1) where Col1 is not null group by Col2 label max(Col1) ''", 0)<>"", vlookup(query({A2:A, arrayformula(int(A2:A))}, "select max(Col1) where Col1 is not null group by Col2 label max(Col1) ''", 0), {A2:A,C2:C}, 2, false), ""))), "SELECT * offset 1", 0), "")*-1)),">0")
Dummy file is here, formula is on D4:

Any suggestions?
