Yeah.... you might want odd groupings and wierd time signatures anyway, in that case the pulse is going to be wierd timing. So if you keep practicing to get it acurrate to every even beat, thats no good if you want to accent the notes in between too.

So IMO you want to try all sorts of odd and even groupings, and positionings on the guitar, that way you can do it all!

Does that make any sense at all? :p
