Okay, I have half an answer courtesy of google. I'm having trouble with the other half.
I've found that "A skater or team’s ranking is determined by the number of points accumulated during the current season and the two previous seasons."
Now, if a skater was junior last season, and a senior this season, do the last two junior seasons count towards a seniors rank? Or are they unranked until they compete as a senior?
Thanks for any help!
