I have started to notice something about GK ratings.

My past 5 or 6 GK have all come in and got reasonable ratings, 6 and 7's with the occasional 8, then after about 15 games they become terrible and its all 5's with the occasional 6 and a few 4's.

I know players can lose form and all that but it's now too regular to be that and looks like GK's are programmed to have ratings like this and there is no reason to their ratings.
