How is 54" size limit being inspected?

At Fingerlakes, after an Inspector tried this method, we informed him why it was wrong and they pulled out a prinout of a 54" circle, which they projected upwards with an ruler. This seems like the correct method to use.

Agreed, that makes much more sense. We never got pulled to the printout at Finger Lakes though. I was surprised that this wasn't standardized between different regional, but how can the cylinder not be measured the same way within a regional?

As I understand it, the measuring tape was supposed to be used to get a rough idea of whether they were at risk of breaking the cylinder. They subtracted a portion from the 54" to account for the circular nature of the cylinder and measured that. If you were close, you'd get pulled to the real circle for a closer inspection.

We were right on the verge as shown in our CAD, we were within 1/2" of 54". We clearly told the inspector this, which is why I'm confused.
