If the doctor of credit post is real, they will be valid for 3 months so using them in increments of 3 would be much better than 5 a month.

Update 2/1/22: Media sources are confirming both of these things: the $5 monthly credit and the DashPass extension through 2024. Two additional details on the $5 monthly credit:

• The $5 credit is for Sapphire Reserve cardholders and it will begin in April 2022 and continue through December 2024.
• The $5 credit expires after 3 months. This makes it possible to easily use them in $15 increments four times per year. Much more useful than $5 expiring each month.
