The post that was quoted here has been removedIf you go to a player's homepage, it will show their opponents' average rating for the last 90 days. So, player "A" could have the exact same rating as player "B" , but have faced much tougher opponents in the last 90 days. So , as Duchess64 says, there are statistics involved...
@jb70 saidThe website's Terms of Service don't seem to mention sandbagging. I find this curious because they do bar use of computer analysis engines and getting advice from third parties.
I gave up Clan playing because I lost all confidence in the TER being an honest indication of the ability of a clan player. Players shedding points in non-clan games to lower their rating.
I've been losing tournament games on here when the tide suddenly turns and I win.
And so I go look at their profile and scroll down and say yes just as I thought a clan player.
So to all the clan players who have donated points to me over the years- thanks but no thanks.
