Perhaps someday in the future, we'll have a complete operating audit of every line in and out of service.

Considering the cost of hard drive capacity, it's somewhat surprising that we don't see more in the way of temperature and pressure tracking.

However, I don't expect we'll see wide-scale deviation from the standard working practice of 7000 cycles until such an appreciable amount of information can be obtained.

But I also note that no facility in the world will be completely demolished and replaced after 20 years on the premise of 7,000 permissible cycles, either.

So I don't think I'd want to readily stray from 7,000 cycles being the standard in the absence of better information. I've worked on lines that are 50 years old, and while I have a good feeling that it still is nowhere near 7,000 cycles, I do not have any desire to be seated before a panel of jurists or a judge to explain why I elected to deviate from standard practice without that specific criterion in hand.
