You can't really predict anything with altcoins so it's hard to compare tomorrow to yesterday. But considering the same moments in time: if we had bigger overall hashrate today/yesterday, our profits would have been bigger. The same goes for the future - we would have better profits with bigger hashrate than with smaller hashrate. At least up to some point (I guess with 10,000 MH/s you're too big for some smaller coins that give us some profits now).
