### Stopwatch timing

Posted: Sun Jul 14, 2019 7:54 am
I'm doing some calculations for average game times for pinball machines I'll be playing in a few months by using my phone's built in stopwatch (as part of the clock application), and I'd like to create a formula that allows me to calculate total time and average time. Is this possible, and if it is, what formula should I use?

You'll need to consider what information you need to store to achieve your goal. What is meant by "total time"?

If you mean elapsed time for one game, then you'll need to store start and finish times and subtract start from finish. Supposing your start time is in A2 and finish time is in B2, then in C2 simply =B2-A2 would give you the elapsed time.

If you have a column, say C with a number of elapsed times, you could use the AVERAGE function to get an average. This is all fairly basic stuff.

Total time is the time taken to complete a whole game of pinball, including extra balls. I have made a custom format available with hundredths of a second capability.

By the way, I do believe I have more than one account, and the email address I currently use is no longer in operation. I cannot change my nathandiniz AT comcast dot net email address to my main email address, or an alternate one.

Hi,
lets say you have your stopped periods in cells A2:A40
then you can use:
Code: Select all   Expand viewCollapse view
`=AVERAGE(A2:A40)`

and
Code: Select all   Expand viewCollapse view
`=SUM(A2:A40)`
