Core Exchange Rate (CER) of bitAssets whose BSRM is individual_settlement_to_fund or no_settlement?

[abitmore]

For a bitAsset whose backing asset is the core asset (BTS) and BSRM is individual_settlement_to_fund or no_settlement, when price of the core asset falls, essentially there is a floor for current_feed.settlement_price, however, current_feed.core_exchange_rate does not stop falling.

In practice, when a bitAsset is globally settled, price feeder producers are asked to feed CER with max(gs_price, feed_price * a multiplier). I think the same can be applied to the bitAsset whose BSRM is individual_settlement_to_fund or no_settlement too.
