I know in your example, you set "up until this past year" as 3years ago up until the past year, but is there a time limit to that? like can we go even further back? this nuance is a bit confusing
Relatively uncommon (3% of games the last 3years were "misc" games) but enough that you should be good at them. Just like lots of things that "rarely" happen on this test, they don't until they do... then you'd better know what you're doing.
