It is obvious that the count of the greatest residue is equal to the  
total number of residues
if all the residues are identical.

Presumably, the parameter threshold should be
0 <= threshold <= 1.0

I really don't know.  So this is just my feeling,
but this could be simplicity, readability, and extensibility...
Did you compare the performance with linear search?
