The numbers on a royalty statement are actuarial, not actual.
They represent a kind of best-guess approximation of the copies
shipped, sold, returned and so forth. Actuarial accounting works
pretty well: well enough to run the juggernaut banking,
insurance, and gambling industries on. It's good enough for
divvying up the royalties paid by musical rights societies for
radio airplay and live performance. And it's good enough for
counting how many copies of a book are distributed online or off.

Counts of paper books are differently precise from counts of
electronic books, sure: but neither one is inherently countable.

And finally, of course, there's the matter of selling books.
However an author earns her living from her words, printed or
encoded, she has as her first and hardest task to find her
audience. There are more competitors for our attention than we
can possibly reconcile, prioritize or make sense of. Getting a
book under the right person's nose, with the right pitch, is the
hardest and most important task any writer faces.
