priority-members of "config service" vs "config members" at SD-WAN

[HT_JDC]

Dear Experts,

At SD-WAN configuration, when manual mode is used, is "set priority-members" of "config service" stronger than "set priority" of "config members"?
I tried several values and it seems to be such thing.

Also, how should we use the both, including use of other modes?

Thanks in advance,

config service is prioritized before config members.
