Aggregate price data

When using the /groups endpoint, there is a unique group called Aggregate. Data returned for tickers in this group uses the aggregate price data across all pools on Cardano for a given pair.

How is this calculated? The token reserves for each pool of a given pair are summed together as if they were all in a single pool. This can be thought of as a “weighted average” of all pools on Cardano, and will be more representative of the global price for a token pair.
