iDine/Rewards Network - Delta users: what's their posting time ?

Looking at the NWA-DL 'double-miles transfer' offer .. which, to participate, requires that our shiney new SkyPiles accounts must be "Lifetime greater than Zero"; the perfect opening for a string of coffee-buys (yes, we have card#s available) !

IME, IHG Priority Club has been posting 'end of the week' ~ NWA runs 'end of the month'...

So, the question: what time-frame might I expect for Delta ?

Thanx

RN dines with DL post normally about 10 days after the date of the dine.

Thanx ;) Should make this tactic do-able ^
