        <p>Daily summaries were introduced in V3.0 (December, 2014), to speed up 
            certain kinds of aggregation calculations. They were designed to "weight" values
            depending on the time length of the archive record that contributed them. For example,
            shorter intervals contributed less than longer intervals. This was intended to enable
            changes to the length of the archive interval.</p>
