Speaking as a physicist, the surrounding tiles DO have an effect.  They 
prevent the stringers from deforming in the horizontal direction 
perpendicular to the line of stringer/tile contact.

But you may also be right.  Mark, please ask this question of a flooring 
engineer.  Broken arms, backs, ribs and worse are not worth it.
