Also relevant is that the status in force for benefit purposes in 2019 carries through January 2020 (largely to allow for delayed adjustments like ORC etc.).

In that case (and if I've been understanding these threads properly), this could happen

* finish 2019 with 45,200 MQM
* start 2020 with Silver status and 20,200 MQM, but still enjoying Platinum benefits (I think I got from your post that he had Platinum for 2019)
* if Amex posts the 5k MQM by January 31, that turns into Gold status and 200 MQM plus earnings from 2020 flights
* if the posting is further delayed into February, then it's Silver status and 20,200 MQM plus earnings from 2020 flights until the Gold status in the previous bullet point kicks in

One interesting question would be if it's possible in the last scenario to get bonus RDM that you would have earned on flights in that February interim period of Silver credited or have any fees that would have been waived for a Gold in that period refunded.
