I'm looking to find the average working days from the start date to the date of the job's first review. The first review could happen in two different ways represented in two different columns, a work in progress review, or an official review. Depending on the complexity of the job they may or may not need a WIP review.
I understand how to find the networkings days, but I want to be able to use the wip review date and if one isn't there use the official review date instead to give me the networkings days
Example of the sheet would look like this:
Is there a formula that could do this automatically?
