derivedETH calculation

[kaseyriver11]

The derivedETH for WBTC shows up as ~60. But WBTC to WETH is ~14.

Is there a definition of derivedETH somewhere? I thought it was the ratio of one token to WETH.

Query:

    query = """ query {
    tokens(first: 200, orderBy: volumeUSD, orderDirection: desc){
        id
        symbol
        name
        derivedETH
    }
    }
    """

Table:
