  Well then what's all this about "i want random values with sum 15" and "for this i need small randoms times?"  Why must they have a sum of 15?  What is "random times" about events that are spaced evenly apart by .15 seconds each?  That was certainly misleading.  It sounded just as though you wanted the total time spam of the 100 successive events to be 15 seconds but that the timing was otherwise random.
