I guess I would also suggest, again, run some samples with known data sets
and see what you get(RSSWKDSASWYG). You would want to do this anyway if you want to insure
your real data is being used reasonably. You still need to have some way to check your
opinion from the expert mentioned above and known data will help there too. A factor
of 2 often shows up from just looking at pictures once you have some intuition. I've
often been wrong on intuition, but chasing it down and proving it helps you learn a lot :)
