No, you are still wrong. There are many people misunderstand the explanation of the note1 same as you. The figure is already included both primary and secondary applicants.
Which means, the figure is already added up including primary and secondary applicants.
887 visa application is basically lodged at the same time, so regardless of the number of applicants included in the application, the total number is just 1 application.
The application number is not calculated separately added up primary application and secondary application. It is just one application
It's not a reasonable calculation at all :D, rather, it's just a calculation with wishful thinking
Anyway, about 600-700 applications were cleared within a week with 9-10 case officers based on the data between May and June.
And still seems like over a few hundred applications are cleared weekly basis, so I assume that all the left over applications will be cleared in very sooner future if immigration keep maintaining the processing speed continuously.
Finger cross and I can't wait to see the applicants of June / July 2020 grant news
