Scores at local competitions are not comparable both for each other and hi-level (like Nationals) competitions.
Scores may be both higher or lower. I remember Summer competition at 2012, where all the skaters had very low PCS (significantly lower than the same skaters obtained at other competitions, including Nats). Scores because of this were low.
Yes, they are not perfectly comparable to each other and isn't a perfect indicator to Nationals.
Still, I do still find it noteworthy that we're seeing some 60+ scores from a number of couples; not just a few. My hope is this level of skating continues.
