I thought NEC specified the opposite, specifically that
ground rods had to be at least twice their length apart,
in order for each rod to have its own independent
connection to ground.

In other words, ground rods spaced closer together than
twice their length will not result in as large a reduction
in ground resistance as ground rods spaced the recommended
distance.
