First off: Welcome to the forum, sir.
If the FSSP performance graph is any gauge, the steady upward spiral of FSSP gains looks more like a muscle-in to the NO majority, and there doesn't seem to be any resistance so far.
Would that that were true. But a look at what evil the current occupant of the Throne of St. Peter has done to the Franciscan Friars of the Immaculate shows that there is a great deal of resistance to the return of Tradition, and at the very highest echelons. It's going to get much worse before it gets better. My closest friend is an FSSP priest, and I get the distinct impression from him that he and his brothers feel the Sword of Damacles (read: Bergoglio) hanging over their heads.
And, as an aside, I think one of the worst things wrought by Summorum Pontificuм (perhaps worse than any good that was done) was the introduction of the phrase "Extraordinary form" to describe what is, in fact, the Mass of Ages; the true and only Rite of Mass of the Latin Church, as codified in perpetuity by Pope St. Pius V in Quo Primum. The notion that a scripted, Protestantized liturgy, fabricated by a Freemason with the help of Protestant heretics, and never legally promulgated, could ever be an "ordinary" or "normative" form of Mass is utterly absurd and, frankly, repugnant.
A book I would strongly recommend hunting down (if you're able) would be
The Great Sacrilege by Fr. James Wathen. It's the first critique of the Novus Ordo ever published (at least in English), and shows an insightfulness and prescience that, considering it was written all the way back in 1971, is all but prophetic.
