Number of Facilities?

[afried]

I applied the latest patch to the game
and started playing my first game.

I noticed when colonizing planets that
the number of facilities available varied greatly(sometimes huge planets only allowed me 5 facilities whereas small planets would
sometimes allow 10 or 15 facilities.) Is
this normal? I thought tiny, small, medium,
huge, etc. had the number of facilities
fixed on the planet.

Thanks.
