Can I optimize further?

Trying this with Hashcat 6.1.1: 

hashcat.exe -m 1800 -a 0 -o cracked.txt hash.txt -O --force --status -w3 --remove --potfile-disable -r rules\rockyou-30000.rule rockyou.txt

I've tried reading the manuals, wiki's and googling- took a while to get to this point and make things work. 

I see this as a result:

Is there anything I can do to further refine this job? I seem to be missing key elements to narrow things down given the estimate of 5 years to complete. 

I appreciate any and all constructive advice others with more experience are willing to share. 

Thank you.
