----------------------------------
Hi [~xushiyan] , I can do this improvement, but I have a question, how to tell
the avg value is set by user or is default?

> Propose to respect user setting by following the precedence as below

> 2) if user not setting it, infer from timeline commit metadata
> 3) if timeline is empty, use a default (current: 1024)
