1) Are EQD's based on calendar year or statements? If my statement date is the 6th of the month, will spend between December 7 and December 31, 2018, be credited to 2018?
2) Are they posted based on the statement - I assume so - so if I go over $50K (I've already hit $25K) on the 8th of the month, the clock starts the 6th of the following month?
3) The Barclay's site says EQD's are posted 6-8 weeks after I hit the requirement. Say I have 200K EQM's and $8,999 EQD's as of October 4, and I hit my spend requirement on my October 6 statement, but don't fly anymore. Will I get promoted to PlatPro "6-8" weeks after October 6?
4) For purposes of rolling 12 month EQD, will that also start on the posting date?

I expect to hit 75K EQM's in December, and by then to be between $6 and $9 EQD. I can go over the $50K spend whenever I want. I'd like to go over $50K as late in the year as I can (to keep the rolling EQD for next year) and not "waste" EQD's for a time period when I'm not PlatPro so EQD's don't matter for upgrade priority.
