Need to calculate the average amount of days it takes to complete a specific task

Hello,
I am working on trying to figure out the correct formula to use to find the average amount of days it takes to complete a specific task.
I have multiple types of tasks on my sheet and created an automation that stamps the date it was completed. I need to now find a formula that will sort the average amount of time for each of my tasks separately.
Any help would be very much appreciated.

Hi @JGrison,
- Add a new column to your sheet, let's name it "Duration".
- In this column, for each task, you will calculate the difference between the start date and the completion date. Assuming your start date is in column A and your completion date is in column B, the formula for each row in the Duration column (let's say this is column C) would look like:
Duration@row==[End Date]@row - [Start Date]@row
3- Create a column for task type call it "Task Type"
4- use the following formula to calculate the Average for completed activities type "A" For Example
=AVG(COLLECT(Duration:Duration, [Task Type]:[Task Type], "A", Completed:Completed, "completed"))
the following is a screen shot for sample sheet:
