請問關於485 LUD changes

there are 2 soft LUD changes on our 485 last week. however, no further change on following days. I did some research on a few immigration forum. seems to me for cases recently approved, there is about 10 days between LUD change and approval. appreciate if you can share your insight.

btw, our case has current PD and name check > 180 days, which means it is eligible for approval
