Feb 05, 2019 Cylinders are just too unreliable to answer those kinds of questions. Relying on the cylinders may actually give you a false positive that everything in the field is ok. There are other ways to get these indicators. The frustration of the lagging indicator. You have a limited number of test cylinders, and the labs test them at prearranged times.
