Unless you know what experience I have in PERSEC perhaps you should not assume that I have not done ALL the things involved in background investigations. No system is perfect and this will not catch 100% of the concerns. I have caught many things myself through cross referencing. The old PRs also did not catch 100% of the issues, Everyone has a viewpoint based on their own experiences, there is no right or wrong answer, only the goal to be more efficient and enable those who need clearances to get them expeditiously. CE will require boots on the ground to follow up on issues and interview subjects as needed. We can agree to disagree on some things and agree on others professionally.
