Has anybody ever been able to discern how UA determines the order in which it ships kits?

I started crediting to UA in 2018, and achieved Gold in September, Plat in October and 1K in November. I don't remember receiving as much as an email about crossing those thresholds. For what it's worth, my 1K card from the app still has a 01/2019 expiry, similar to some of the posters above. I will wait patiently.
