I don't know how to do it in Google Sheet, but in Excel I did a test though I don't know if it can be seend by everyone. The point of is it to add minutes seconds and milliseconds in 3 different cells (6 altogether when considering fastest lap and total time), then using the concatenate function to display it and converting each of the times to seconds, before multiplying fastest lap by number of laps and doing the subtraction. since it comes out as a fraction to 3 decimal places, it can be multiplied by a thousand to make it a whole number.
