That is interesting analysis. I did submit 485 J in 2020 since I moved companies (after responding to an earlier 485 J RFE in 2018). If I remember correctly my application was in NBC. I would not expect an RFE for 485J, but for medicals may be. We will see in the next few months. Ironically the 2018 485 J was indeed approved (and did receive approval), where as the 2020 485 J is still in process.
