I second this change...

... and this is information most members of that section's target
audience won't care about.

Remember that there is such a thing as too much information; people need
to be able to digest the package of information we provide them with,
and this section is part of the docs intended for people who aren't
accustomed to heavy meals.

I guess the reference section about rotations would be a more suitable
place to go into technical details.
