Let me introduce you to my style of Power Rankings. It’s not perfect, but it does work out pretty well except in some instances.
The formula for Power Rank Points (or PR Pts.) is (ROW+Goal Differential)*Last 10 Win %.
For the teams that have 0 or less PR Pts., it becomes somewhat skewed (such as when Edmonton and Buffalo had a 0 W% for a while during the 2014-15 season), so I have to either evaluate it myself to rank the subpar teams.
Hope you all enjoy!
