> are just drinking more often but smaller amounts?

Probably. I don't measure my water consumption, but I'm guessing that I drink smaller amounts. Even if my average hydration level is the same, it never goes too low this way, which means that I feel better.

I don't have any objective way to measure the health benefits of drinking a certain amount of water, but it definitely makes me feel better to be more hydrated, so I'm guessing it's good for my health.
