Monthly GIR data

Happy 2022 to the forum and Dimagi team! Wishing everyone success and good health in 2022.

Is there any documentation on the monthly GIR data? I want to understand the metrics output, in particular?

Using and Performing
Not Performing
Inactive and Not Experienced
Not Experienced
Not Performing and Not Experienced
D2 All Possibly Exp Users
D5 All Active Users
D6 All Active Users Current + Prior 2 Mos

Also, for active users, are they counted if a single form is submitted during the month?

*just bumping this in case it has been lost, thanks!
