How long is it taking these days to get Medicals RFE after PD becomes current

How long is it taking these days for USCIS to send medical RFE ?
The Medicals were originally submitted in 2020 November when I-485 was filed concurrently. The dates were current in 2022 for a while but it retrogressed and has become current again in March Bulletin.
We have new medicals done again . should we proactively send the medicals or wait for them to RFE for Medicals. Stressed out .

If I was in your place, i would get two copies of medical from doctor and then send one to USCIS without waiting for RFE.

The second copy would work as a back up in case they send an RFE.
