The Top 25 (usually) has 25 names on it. Only a few times, when there’s been a tie at the 25th spot, has it ballooned up in size. This year, like many recently, the line between 25 and 26 is impossible to see without some decimal places.
We use a weighted average of the votes when calculating the official list. This calculation method is the only change we’ve made to the process over its history. The method is simple: votes are made 1 - 25 by each voter. Those votes are then converted to their reverse values where all Auston Matthews votes have a value of 25, down to a value of one for the votes in spot 25.
