Average Time Since Modified - Sheet Summary

GScottMiller

I am working on a sheet and I'd like to get an average days since modified across a sheet using the system modified date column.

I came up with the following, but im getting an 'invalid data type' error.

=AVG(COLLECT(NETDAYS(Modified:Modified, TODAY()), Status:Status, "In Progress"))

I had this working utilizing a helper column that was just days since modified vs today, but that was refreshing the entire sheet every time we opened it and it checked what day it was. I guess the formula when it checks today, it 'modifies' it and then resets its value haha.

I could use help with either my formula, or with a helper column that wont trigger a modification 'event'

I am struggling to get this formula to work. There very well may be a way. However, one workaround could be to create your own custom "Modified" date column. It would need a workflow set up to trigger when anything changes in a row (except your helper column that calculates net days from today) that a date is recorded in that column. This way, you can keep using the helper column method and your modified column won't change with it.

Hope this helps!:)

Oh yeah, thats an interesting idea, something like a trigger when a comment is made, or when a date is changed? Then log todays date in our new modified column?

Yeah I'll give that a shot!
