Please(!!!) correct me if I am wrong, but didn't Bishop Williamson state that as time goes on, there is less and less of a chance that the NO sacraments are confected, due to the fact that there is less and less of a possibility of a valid Episcopacy and valid ordinations due to the dying off of traditionally consecrated Bishops and priests. ( as well as lack of proper intention due to poor priestly formation).
Not trying to put words in the good Bishop's mouth but I thought that's what he said.

I think he did say that.

But do you understand the difference between "some % doubtful" and "it failed"?

Most sedevacantists don't even look for 1% Catholics in the Novus Ordo. They treat them all as literal Lutherans. All the priests (whom they call "presbyters") all the bishops, all the cardinals, etc. They totally write off 100% of the Conciliar Church. When a Novus Ordo comes to their chapel, they treat it like an actual conversion from a protestant sect (not just a "trad-version" or "discovering Tradition") and require abjurations, renouncement of heresies, etc. They require new converts to confess how many times they attended the Novus Ordo, how many times they received communion in the hand, how many times they acknowledged the "false pope", etc.

Bishop Williamson doesn't do this. He conditionally ordains and acknowledges validity issues in many of the sacraments because as time goes on, the "intention to do what the Church does" will be less common, as priests are formed differently.
