For me, AMEX MR points generally show up within 3-10 days of when I pay my bill. However, it is inconsistent and confusing; I think it depends on the day of month that your statement closes and when you pay.
AMEX Starwood Points (which are also more valuable) show up within 2-3 days of statement closing, even before I pay my bill!
