Advanced Explanation CoinDaysDestroyed_excl_churn_inLoss is reffering the concept of and Coin Days (CD) and Coin Days Destroyed (CDD), originally mentionned on Bitcointalk forum in 20211.

• Coin Days Destroyed measures the number of Coin Days that were set back to 0 by the spending of the UTXO. This metric helps to identify periods where old coins, often associated with HODLers or Long Term Holders are spent, whick can deliver insights about he market behavior and sentiment.
• CoinDaysDestroyed_excl_churn_inLoss tracks the amount of CDD that were destroyed for every UTXO having a spending price inferior to its acquisition price. It can serve to identify the tendency of loss taking to be dominated by Long Term Holders or Short Term Holders.
