Putting extended long OCONUS

Just a question about the OCONUS listing. AFPC states putting extended long on standard tours gives you a better chance of getting selected, but when you select it, it doesn’t say “currently advertised” on your listing. When you just put standard tour it does. I just want to make sure you have more of a chance when you put extended tour, it gives you a better chance so I’m not wasting all my choices where I put it. Any insight would be great. Thank you!
