I meant tighter guarantees of the complexity of the algorithm, in big O. 
The customary quicksort is usually O(NlogN) on most sequences, but it 
can be as high as O(N2). The quicksort variant I have has a guaranteed 
worst case of O(NlogN). The price for that guarantee is a larger K 
overall. Which if one is using objects for which the comparison is 
expensive is a better trade off.
