The "1st Pressing" LP Hysteria- Is the terminology wrong?

I sell LP’s on Ebay and I find myself having to correct potential buyers all the time because I believe that other sellers are using "1st Pressing" and "Original Release" or "ED1" interchangeably and just confusing a lot of buyers.

I use "First Pressing" to define those records that are pressed with the first set of stampers for a particular label release. In other words, later (than the original) label release can have first stamper codes but not be an original first pressing. An "ED 1" or "First Release" can have first stamper codes or later stamper codes.

There is also a mistaken belief that "First Pressings" sound better than later pressings, but that is another rabbit hole. The biggest problem with that belief (condition aside) is that there is no way to know whether the record was pressed early, when the stampers were fresh or much later when the stampers were at the end of their useful life. This is why I put importance on true "Promo Copies" because it is usually true that these promo records were pressed while the stampers were still fresh.

Thoughts?
