What test provides the most accurate estimate of vacuum bottle life?

Any assistance would be greatly appreciated.

I would assume the answer to your question is MAC testing. Unfortunately, I have never been able to perform this diagnostic trending test, but have only heard great things about it. My understanding is you set a baseline and then can trend over the life of the vacuum bottle for the actual vacuum leak rate. I do not believe you can get immediate measurements without a trend. See below links for more information:
