In that case yes - but with longer bars, I'd try to find a reference
in between my notes. Let's take Paul's nice example. To play the 9
1/2 part, I'd really rather not count to 19, but to 9 - and then I'd
expect the next bar to start *in between* my 9 and 10; on the "and",
that is.

Well, why don't we ask someone who actually plays this kind of music
seriously? I can only tell you how *I* count when dealing with
complex rhythms - and I don't do it all that often. (I've done 5 + 4
beats per bar and that sort of stuff, and it's basically the same
thing; you need to "lock" on more relations that 1:1, or there's no
way you can both "drift" and not at the same time.)

Why not?
