Scientific relevance of the Equivalence Principle
(III)
fractional differential acceleration between bodies of different
composition falling in the gravitational field of a source mass
g*= g - 1   g Eddington parameter

g* < 10-3   by post Newtonian or pulsar tests
Da/a < 10-12 ¸10-13  by EP tests Þ   g* < 10-7 ¸ 10-9     or   10-8 ¸ 10-10
The superior probing power of Equivalence Principle tests is
beyond question !!!!
