The way to get a random sample of all users would really be to bundle  
your code with a distribution and do the study with a large number of  
users. Adding a sample here and there, especially if you ask users  
like me, doesn't make sense methodology-wise.

But to be honest, one would have to talk about the goals of this  
endeavor first. Key bindings should be determined by what people are  
used to. My conjecture: it takes longer to remember an unfamiliar  
command than to type a familiar two- or three-stroke command. I could  
dig out some references from the memory access and UI literature. We  
could build an ACT-R model for it, or run a little study to prove it.  
(I have time for none of the options.)

But essentially, that's why Aquamacs sticks to (presumably) familiar  
Apple key bindings, which have probably been selected according to  
their general frequency. And that's also why Emacs sticks to its  
common key bindings, which do not match the use frequency, but which  
have been learned by its millions of users.

If you'd like to help, given the knowledge gained from your use case  
study, I suggest you help port something like Aquamacs to other  
systems (that is, Windows and GNU/Linux). That way, you'll ensure  
that short key bindings are available for frequent commands ( the  
ranking of less frequent commands will differ more between people,  
and their frequencies will have a much higher error in your study  
with n=1.)
If ported to all three major systems, moving it to a GNU variant will  
be a more realistic proposition. (RMS doesn't seem to object to UI  
changes in an Emacs variants. It's the fact that it's only available  
for the Mac that he doesn't like, and I have to agree with him.)
