That's only true for a nominal 24 sat constellation.  With the
current 30+ constellation you can get up to about 15 in certain

That's not the same as they'll do you any good if their geometry
is poor, but you can track them nontheless.

Never attribute to malice what can adequately be explained by incompetence.
