Jira Advanced Roadmap vs Roadmap - Ranking

[Pou Yang Gan]

Hi everyone! I hope you are well.

I created 2 projects and experimented with 2x Advanced Roadmap and would like to understand if the following are correct in terms of ranking:
1) Ranking changes in JIRA Advanced Roadmap will not affect the project roadmap's ranking
2) Ranking changes in the project roadmap will change the ranking in JIRA Advanced Roadmap if the ranking within JIRA Advanced Roadmap has not been change manually on the JIRA Advanced Roadmap
3) Ranking changes in one JIRA Advanced Roadmap will not impact the ranking in another JIRA Advanced Roadmap

Do other people have the same results?
