I'm at 22k of my 30k, with a consistent $2k-$5k month. I was targeted for 9/1-10/31.
My wife just got to $2k for the 100k promo earlier this year and was not.
She was previously targeted for the 5k bonus for authorized user back in ~May while I was not (similar activity at that time).
Who knows... I'm pretty happy though.
