Weibull modulus

[Andrew Norreys]

Can anyone tell me whether in a series of numbers of which there are
repeats, do the repeated numbers hold the same rank, or does the
numbering carry directly on regardless of value?

I seem to get conflicting arguments from people and by altering the way
the ranking is done, can get a significant improvement in the calculated
modulus/expectancy.

Thanks
