DNS Zone aging/ Scaveging 2008 R2 integrated

Hi all,
I'm about to make a change to the Active Directory integrated DNS scavenging which is currently set at:
No-Refresh interval = 1 day
Refresh Interval = 60 days.
I'm trying to bring this into alignment with other domains and was planning of changing both fields to 7 days. Can anyone see a problem with doing this?

Only problem I see is with DHCP lease time. Consider use same time on both or bit high on DNS scavenge, on this way when a lease ends, will be remove from DNS.

The DHCP lease is set to 2 days.

Thats OK, you can set on 3 days or 7 if you prefer. If the host exist and ip changes, DCHP or client itself change dns host record. If host not renew lease (because is turned off or whatever), after 7 days will be deleted (if you set on 7 days). You have 7-2= 5 days that DNS will resolve a host thats is not on the network, nothings happens.
