Thirty to forty team regionals tend to have a higher representation at champs. (The largest Canadian regional last year had 48 teams, the smallest couple only had 30. Not picking on Canada, but based on the maple leaf I'm guessing that was what you were referring to.)

Past that, week 1 regionals are over-represented and week 6 regionals are underrepresented.

That's simply because each regional is allocated 6 slots and a maximum of 3 wildcards regardless of size and once a team has won, winning again at another event can prevent another team from going to St. Louis.

A week 1 regional will always send 6 teams to worlds regardless of size.

Last year, North Star in Minneapolis (week 6) sent two new teams out of 60 teams attending to worlds.

So, what would I do?

Assuming a goal of 10% of regional participants moving to worlds.

Set a "wildcard threshold" of floor(regional participants /10)

So, if the regional has 30 participants the wildcard threshold is 3, if it's 67 it's 6.

Now, at a regional as many as six teams may go on to worlds. If the winning alliance, Engineering Inspiration, Chairman's, and Rookie All-star are all different teams who aren't already going to worlds they all go.

But if those winners or some of those winners are already going to worlds you'd look into creating wildcards.

Let's say that of those 6 winners there were 4 already going (only generating 2 new invitations) either because of duplicates at the event or previous wins.

So, if this is a 30 team regional it would generate 1 wildcard slot, if it were a 60 team regional it would generate 4 wildcards.

The first 3 wildcard slots are easy and already defined, that's the members of the finalist alliance.

Past those first 3, I'd suggest moving down the seedings established by the qualification matches so that the highest seeded teams who weren't already going get invites.

It would still be advantageous to go to a week 1, or 30 team regional, but not quite as much as it currently is.
