If you take July 2018 inventory and add the cases till April 2009, you will get 2260 cases. EB2I dates were 8th May, 2009 in September and that is the 5th working day of a 20 working day month. So that's 25% of May 2009 cases which is about 360 cases. This takes the total to 2620 cases. I don't know how many CP cases are, but if you add 10% more, you get about 2,900 cases. When the dates started moving last year, EB2I was still ahead of EB3I, so you cannot discount EB3I to EB2I upgrading cases. Add the unknown number of people who filed for the first time, the number increases further. You can take credit for the time between the inventory publication (July 2018) to visas available for the FY. This can vary from 500 to 700 depending on how you look at it.
