Well perhaps someone at UA is reading FT?
Just got an email about this, outlining the offer and terms etc.
One thing that is spelt out in those emailed T+C that several here have asked about re short flights and 500 mile minimum etc is here:
"Double Elite Qualifying Miles in this offer are defined as two times the actual flight miles posted to your account for flights taken during the promotional period."
