Well, I doubt he expect a 40k to be king, but rather just have a chance at the final event.
I mean compare this grouping with what is shown here:

That group doesn't even have enough people to fill the 128, when, according to what OP said, there is at least 1k participants in his group.
Personally, I think each grouping should have between 300 and 600 ACTIVE qualifying participants. That should give a interesting but not excessively difficult race for 128 for everyone.
