Wayfinder Rating

Can we get some precise information on what causes the wayfinder rating to change so easily? Has the algorithm changed recently? I was always constantly at Great, but as of the start of the year I've been jumping between Great and Good but haven't changed the way I review or frequency of reviewing. Very annoying
