I can't at y'all dismissing a song because it's not #1 after 3 weeks.

Y'all need to calm down. "XO" was released right at the beginning of the Winter freeze, and it's doing perfectly fine.
She'll most likely perform it at the Grammys, and the boost in sales + the increased airplay would be enough to send it to the top 10 for like 2-4 weeks at the least.
Anyway, I think she should send "Blow" to pop radio in April 2014 (with "Partition" to Urban/Rhythmic), and then "Pretty Hurts" to pop radio in July 2014 (with "Mine" to Urban/Rhythmic). Or maybe, send "Mine" to all formats in October 2014, followed by "Jealous" as the 5th pop (7th overall) and final single in January 2015.
