Quick reminder that I have a solution for this. I have a code that runs regularly and applies formulas to various projects and tasks. I personally use it to compute an invoice amount in euros even though I sometimes invoice in dollars, my clients use it for ICE score, rice score, weighted volume etc.
And I just updated the code to take into account created date, completion date and completion status. That allows me to have a column with “Created since X days” and “Completed after X days”.
