What is the expected time frame for FAA knowledge test results to show up in IACRA? I just passed my Part 107 Remote Pilot's knowledge test this morning, and I noticed that IACRA indicates it may take up to 48 hours for the test records to show up.  Does it always take 48 hours or is it sometimes faster than that?  What is the soonest that I might reasonably expect the test results to appear?  

Bonus points if anyone knows why it takes so long, but I realize that may not be something anyone knows about (or can talk about).
I passed back in December 2016.  Took 3 days to get temp license and about 90 days to get my perm license.  Took me a week of study watching Youtube videos on weather and sectionals, in conjunction with UAS107 prep app (https://play.google.com/store/apps/details?id=uas107.openrobotix.labs&amp;hl=en)
