It's been a while since I've had to worry about this so it might be bad, old information. But it feels like when things are going well, you're going to overfill the stadium. So, this might be the best chance to take advantage of those higher attendance figures. Then when you're getting knocked around in V for a little bit, you might have a harder time filling it even with the 10% more supporters.
As an aside, I've always thought the spelling of "whale" in that context was odd (albeit correct). I just have this image of someone hitting someone else with a giant cetacean. And I would totally watch that in a 12K, 20K, or 40K stadium
