Our American colleagues are trained to fly an 'overlay' just like most other "glass" operators. Jazz guys and gals know it as the SCDA. The ERJ135/145 every bit as capable as the CRJs, Boeings, Airbuses, you name it.
VNAV guidance for a NPA is too easy. Much easier than the old 'dive and drive' NPA. Highly unlikely a BC, VOR, or NDB has anything to do with it.
NPA proficiency, or lack of proficiency is not a likely reason for missing as the NPA is required on all 61.48s AND in Continental Expresss' case, a 121.441.
10,000 hours versus 3,000 hours is a non-starter. Continental Express out of the NE has just as many bad weather days as YQB or any other Canadian airport for that matter.
As for the stat itself, some months you're up, and some months your down. Never shy away from a missed approach when it's called for. That's why we brief it.
