I'm an Actuary and though I've built various packages using MS Office mostly using VBA I would not say I have a software engineering background.
I find index 0 difficult to work when working with arrays in the abstract (maybe something to do with being slightly dyslexic) but in my work I don't find origin 0 a hindrance. Often in actuarial applications the index represents time in a projection of some sort with t=0 being today so it is natural this is the element in the results array.
