Indian Green Card queue movement - visa bulletin

Final action date for my husband’s Green Card is Nov’2018 . As per the current visa bulletin final action date is 01MAR18. Any thoughts on how much time it will take to get to Nov’2018.

At least date of filing can reach to Nov18 around Oct to Dec 2020 for eb1 India in my opinion.
The USCIS accepts date of filing from October generally.
After filing 485 it takes around 9-12 months to get the actual card in hand if the dates do not retrogress.
