I don't think that's enough. In two hours, it's already filled up.
You mentioned the super visa. People come to my office waiting to see whether they can bring in their grandparents one way or another, and when I tell them that, unfortunately, they are not able to submit an application to sponsor them because the quota has been met, they have to apply for a super visa. Bringing grandparents in that 10-year gap can be very difficult, in terms of the cost of flying them back and forth, because they are not able to stay here more than two years.
I'm not really sure I have a specific number for you. The only thing I know is that 10,000 is just not enough.
