Actually, I wouldn't expect that:  the "zscores" aren't a function of smean
or hmean alone, they also depend on each msg's n value (in a way that's
highly dubious in clt1 and clt2, and wholly unjustified in clt3).

To the limited extent that the zscores *may* make sense under clt1 and clt2,
it's the dependence on n that the sense comes from.

If you got the same results by ignoring n completely (which just looking at
hmean or smean does), then that at least confirms that fiddling with n is in
fact of no value in the current pseudo-zscore computation.
