The thing is with players in the RFA age group, their ratings aren't that likely to drop unless they are say...Sergei Samsonov. Also the CPHL does attempt to consider a players entire career, and the last three years in particular when doing ratings.
My rule of thumb is to take the players NHL salary and contract status into consideration and than use 1.5x that as a general guideline for what you should be paying a player as a maximum. Of course with unrestricted status coming down in age in the NHL it no longer apply's to every player like it used to.
