I'm trying to calculate the amount of XP per day I need in order to get to Tier 50. I'm currently about 10K XP away from Tier 32. This means I have roughly 580K XP left.

If I haven't done any of the Week 5 Challenges, that means I'll have about 215K in Weekly Challenge XP and a maximum of 92K XP from Dailies XP. After including Challenges, I will have roughly 273K remaining XP (or 265K XP including the 3% BP bonus).

Since there are 23 days left, I need about 11.5K XP (3 Unrated Games/~1.5-2 Hours) every day in order to get the bare minimum of Tier 50.

Is this math correct? That seems so excessive especially for someone who doesn't live on this game. Why is this BP such a chore compared to other (more fun and engaging) BP's? I understand they're trying to make money by not including VP in here, but at least don't make it a job.
