Do you guys think it will be ok to group all the K240 (Sexttet and what not) together and all the Beyers together!? They have all these different models and it confuses me.

As to your worry, we are only estimating C, it really doesn't matter much, I would stop when any set of C phones (each of them) has 20 or more votes, even if the list of C changes. No biggie, this is all guess work.
So are the numbers 80% (well that's the 80-20 rule which generally holds), 100 and 20 ... these come from WAGs ("wild ass guess") of mine using what is called "power analysis". See Wikipedia or
EPA Statistical Primer - Power Analysis
I'm not sure it's worth studying up on stats -- keep a statistician as a friend, that's the better way. Or marry one. I did. So did my wife.
Anyway back to the thread: hey OP, what's the current tally??
Ah yes, power analyses. I'm still looking for a simple Mac OS X app that'll do that for me. Used to have a DOS one, but those days are gone. Thank goodness for me, the department has quite a few stats-savvy members. So, I didn't bother taking the graduate class.
