I’ve been trying to get an idea of this too. Going off what people have been posting here and from active spreadsheets:
It looks like January, February, & March of 2022 each have around 3k untouched at the moment. Then going back into 2021, December 2021 has around 3200 left, November 2021 has around 1500, and it looks like October 2021 is just under 500. If we add July, August, and September of 2021 it looks around 500 left for all three total.
July, August, & September 2021- 500
October 2021- 500
November 2021- 1500
December 2021- 3200
January 2022- 3000
February 2022- 3000
March 2022- 3000
My NOA1 is at the end of March so for me, I’m estimating there are roughly 14,700 untouched cases in front of me.
Please correct me if my numbers are wrong. But it’s just a rough estimate.
