Ah, that's what was confusing me... if these are empirical equations,
shouldn't they contain just terms and rational constants?   
Why do they have pi in them??  Pi hints at mathemetical derivation.

BTW, the non-empirical, mathematically derived equation for a 
critically damped secondary is  Rl = 2 x SQRT(Ls/Cs).
