I don't think we are sure what you are trying to say here???
Bob has said that base stock is not the end all/be all (paraphrase). It's the total package chemistry.
Checking the board is useful, but only uoa will really tell you for sure what's working for you.
I plan to do a Syntec uoa in the future, but it will be a few months away.
If your're like me and think some oils aren't getting a fair shake, then uoa and submit the results.
