I don't think anyone was questioning her score. I think they were questioning the other player who had never had a top 100 finish in a CTTP, but somehow on sunday was able to take the lead in a monthly cttp tourney (hrm, maybe someone quickly adjusting to non-legend callaways?). Then, for the first time ever, purchase a putter pal (which many members of the club in question use), and then go off and shoot their best single play round ever on the toughest course on WGT. Lot of coincidences there.
And to question the integrity of this club, it seems everyone was cool with one of their most prominent members multiaccounting last year and even qualifying for the majors with both accounts.
