Does anyone have data points for how reliable crediting AS for KE flights is, or how long the partner miles take to post from KE to AS?

I'm flying KE in December (Prestige class with D/I fare codes), and the rather hefty quantity of miles earned from the round trip will put me in spitting distance of MVP Gold 75. I'll need to pay for the last few hundred miles using the EverGreen EQM offer to make it happen, however. (I simply won't have enough actual days left in the year to make a mileage run due to my holiday plans.)

Last December, on a similar trip, a failure by AS to properly credit QR miles (flight time subbed for flight number and no response when I tried to get it fixed) makes me mistrust whether spending any money for miles is smart until I actually see accurate partner miles land in my Alaska account...
