8 ohm nominal impedance/4.69 ohm minimal impedance--is this a bad load (on paper)?

As per usual, I measure once and sometimes cut twice.  I am just curious, is all, as I am doing reading that I probably should have done back in May.  That impedance drop was what was listed by Ern's Corner for the Revel M126Be, and I was just wondering how it stacked up on paper.
