To avoid confusion, please stop using the term girth when you mean width. Girth is the measurement around something and not it's width. It's like saying circumference of a circle rather than diameter. two very different measurements.
For what it's worth, I agree that all magazines seem to have a hard time with numbers. There is a chance this was an honest mistake and not a conspiracy, however. Or their measuring procedure changed and they didnt't detail that. It is worth asking the question and is perhaps worth a "letter to the editor" to bring it to their attention so they can clarify, for all readers, in the next issue.
Kinda why I used it, "girth" makes as much sense as there measurements. I was not using it as anything I care to measure or would hold any value.
