The first assumption to make is that the boxes stay consistent at 12, which prior to the large break in 2011-2012 it was at 13 so who knows if it changes. The second assumption is if the number of days between releases is the normal 70 or if we include having more large breaks (2011-2012 break) which would put the average at 84. Based upon these two assumptions the dub anime would reach today's sub on 9/3/2019(70 days) or 7/21/2020(84 days). At least this can make you feel a little better than the Summer 2021 estimate you established.
