comment Number of Combinations from 1 to 100
Consider this, say I want to create a chemical mixture of 5 constituents (ie I mix together 5 different chemicals) for some sort testing. How many experiments am I required to to run, to cover all mixtures, if I am to create a grid with a concentration step (for each constituent) of 0.5%, noting that in each experiment, A + B + C + D + E = 100%

Yes, and for example (1,99) != (99,1), the case of 2 sets is rather trivial (can do it by hand), but when there are 5 or more sets...

@Omnitic, not subsets, pairs. But I seek to generalize for more than 3 sets, and, where the increment is smaller (say if the set is: 0, 0.5, 1, 1.5, ... 100)

Probably something like the total number of combinations, multiplied by a coefficient representing 1 - the probability of exceeding the limit.

comment What is $-i$ exactly?
Yeah but it means that the reputation 'always goes up'. I wonder if we will see a reputation bubble....
