They come and they go. You shouldn't be so concerned with hubscore. I don't mean to say that hubscore isn't relevant, it's just that it swings wildly up and down, and often changes daily.
I've had hubs that land on home pages, but never have I seen what I though was my best work landing on home pages.
But maybe I'm not the best judge of what my "best" is?
I hit home page status with hubs about animals, so I'm thinking that writing about wildlife is something that isn't being done so much on this site, so maybe I should do more of that. In other words, what it comes down to is this: Write in niches or areas that have less competition in them, and you'll wind up promoted on everyone who follows that topics homepage.
