As I recall, Leupold clearly rates their 2X EER scopes @ 1.7X, and their 4X EER scopes @ 3.5X, on their spec sheets.
Not everyone knows this, but the eyepiece on a Leupold scope, when screwed in, wiil reduce magnification somewhat, and when screwed out, will increase magnification a bit. The reason for the adjustment capability is to sharpen the crosshair for the individual's eye, so there is a limit to how much an individual can change magnification, and still have a sharply focused crosshair.
I BELIEVE that the Lobos had the same trait, but that's been a LONG time ago!
