DNS Scavenging and DHCP lease

Hello :-)
I am configuring dns scavenging in my dns / dhcp. currently the dhcp lease is 6 days, so according to the question https://www.experts-exchange.com/questions/29093013/DNS-Scavenging-Best-Practice.html I've defined the no-refresh and refresh values for 3 days each (50% dhcp lease). So the DNS option "allow automatic deletion of obsolete records" should be set to same dhcp lease (6 days)?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

It should be set to 3days
So that by every 3 days, dns will clean up stale records older than 6 days (3 days refresh + 3 days no refresh interval)
