  The recent development, shows that the Bray-Curtis's formula for similarity
Index (1957), has been applied in various fields like Ecology, Astrophysics,
etc. In this paper, we found the possible boundary conditions for this evolved
formula (i.e. the numerical range in which the formula becomes in-effective to
give the expected result). Here we have simulated the real world data in the
form of normally distributed random numbers, that directly shows the range (or
conditions) at which this formula gives unambiguous similarity result.
