There is a point there. Sinitsina was overscored pretty hard but she is also not in peak shape. Evidently her StSq and choreo especially are extremely rough and she admitted it herself. I think in peak form though pushing 220 internationally is reasonable. She also claims she will jump ultra-c this season (maybe for Nats?) so we cant judge her yet.
I also think Frolova in her 2nd stage showed potential to beat out Kaori on a good day. Especially with Kaori's sub-par programs this season.
Sinitsia and Frolova's score would largely depend on geographical factors. I think score would be similar as to the Russian women's competition. Sinitsina and Frolova don't crawl to a stop when jumping, did relatively well rotating jumps, no glaring edge issues, so this would only help GOE.
Maya was a little high for PCS this is an error, but she is quite a captivating skater. When she skates I have always remembered her performances I can't say that for a lot of skaters. Frolova is maybe like an Amber Glenn, but really consistent (Glenn would be a killer with consistency) and minus the 3A (I like both skaters and I hope it's okay to mention international skaters in this thread).

That's a pretty broad statement.
