How long for AMEX points to show up in Thai Airways ROP FFP??

Just checking if anyone has any idea how long does it takes for AMEX Plat Membership Rewards Points to show up in Thai Airways ROP FFP account after initiation of the transfer?

I called the AMEX SIN office and the guy told me that he thinks it will take 2 to 3 working weeks. I have some orphan miles left in ROP which I am trying to combine it with the AMEX points to make a redemption soon.

Thanks.
