I made the count out to be as Jeri says. It is a relief to know I wasn't inventing the difficulty, but even with the count I usually get it wrong. And yet Dolly makes it look effortless. Another question is whether the whole thing adds anything to the song; would it be as good with a conventional count.
   I assume the other folks who commented don't find it hard, whether through a natural ear or a mathematical brain, but I suspect most do.
