>>>>I was wondering when does the actual upgrades get processed.

As a fellow Gold, my upgrades--if R space is available--for the past few months have happened mid-day (roughly between 10am and 4pm CST) 4 days before day of departure. If they didn't come then, then in all instances F space was below 6 or so. I've had good luck within the 24 hour window, however, when EUA didn't happen 3 (actually 4) days out.
