By the WWV method, I can get the (out of phase) WOW to about 1 every 
four or five seconds; pretty durned close (enough).

With the software approach, any sound card error (which can vary a lot) 
is corrected so any software using it, is dead on.

Bottom line is that unless you're attempting the ARRL FMT, a few hertz 
won't be noticed by most; aging ears just aren't that good a test and 
most software isn't that critical either.
