Interesting dashboard I found online.

Yes, I've made a similar observation but laid it out slightly differently. If you look at the crisis as a syllogism, it would look something like this.
MAJOR: Catholic Church cannot teach grave error or promulgate a form of public worship that displeases God.
MINOR: Conciliar Church taught grave error and promulgated a form of public worship that displeases God.
CONCLUSION: Conciliar Church is not the Catholic Church.
Ultimately, the different positions on the Crisis have to do with the different permutations of accepting / rejecting the MAJOR or the MINOR. "Traditional Catholics" (whether SV or R&R or any other flavor) are all called such because we all agree on the MINOR, that the Conciliar Church taught grave error and promulgated a form of public worship that displeases God. But the division among Traditional Catholics (SV vs. R&R) boils down to contention over the MAJOR. R&R (of the SeanJohnson variety) REJECT the MAJOR and therefore the CONCLUSION, whereas SVs affirm the MAJOR. NOTE: Archbishop Lefebvre himself publicly affirmed the MAJOR (unlike the Johnsonian R&R). He merely shied away from the CONCLUSION based on other hesitancy, namely, wanting to defer the ultimate decision to the authority of the Church and uncertainty about whether some other factor or some other distinction might be in play.
Meanwhile, conservative Novus Ordites agree with the SVs in affirming the MAJOR. Liberal (aka Modernist) Novus Ordites agree with Johnsonian R&R in rejecting the MAJOR, except they hold that the pre-V2 Church was in error (had gone off the rails) and welcome the "correction" made by Vatican II. Interestingly, once you reject the MAJOR, there's no telling which is true. If the Church can go badly off the rails, how can we know whether it was off the rails BEFORE Vatican II or was on track before and then went off AFTER?
