This statement got me thinking this morning and I did a little SQL
hacking...

I "diced" up sector this morning my CT expanded system generator, I
notice that Agricultural Worlds are really rare. I created a
sector this morning and out of 14207 total worlds 134 would be
classified Ag by Book 7. These 14207 worlds have a total population of
468.8 billion sophants.

My system is still currently still in test. I just fixed a bug in
atmosphere and hydrographics generation. My system only generates Solo
star systems so there is a shortage of habitable zone planets. All of
these factors should depress the number of Ag planets, but I don't
expect it to go up by a factor of ten when these problems are
fixed.

I think that the driver for this the fact is the DM of -2 for planets
generated around spectral class M stars. Class M stars are by far the
most commonly generated. It's important because the basic Mainworld
generation sequence has no size DM and imposes a reverse DM on the
star's spectral class when you expand a system by detailing what it's
star is.
