suggest to add below at the end of "Specification" part:

This BSIP provide a general solution that handle the bad debt problem of smartcoins, whether this BSIP will be applied to one specific smartcoin depend on the poll voting result, two poll worker proposals, including FOR and AGAINST, will be created for voting on each specific smartcoin.

To me, this seems to be confirm with the rules of BSIPs.

Ideally, we'd see a paragraph that explains potential risks of this approach to let voters make better decisions.

suggest to add below as "potential risk" if necessary.

One risk is that this BSIP may be misinterpreted as “price manipulation” or even “cheating” and hurt the trust on smart coin.

Actually this BSIP may lead to obvious higher feed price than market price when bad debt emerge, but this do not lead to hurting to traders comparing to global settlement. The key point is that under this BSIP the global settlement price and also the feed price can still come down, however under global settlement the settle price will be fixed.

To the traders that issue force settlement, this BSIP can provide better price for smartcoin holders to settle.

To the smartcoin holders, this BSIP can bring less devaluing of the smartcoin comparing to global settlement.

The only groups that may be hurt is the debt position owners, their debt position may be settled at a lower price comparing to global settlement, but this is fair and is irrelevant to “price manipulation” or “cheating”.
