Hi I shoot (for private use) appr. 1 roll of film a week. If the shutter lasts 100.000 cycles, it would last me appr. 50 years! Pretty good, eh? That's is if I don't fire it without having loaded the camrea with film - which I do frequently...
I only had a shutter replaced once - a peace of tape got stuck in my Z1 - I tore the leaves apart pulling out the tape! That cost me appr. 200 $, but I gues my Z1 was worth that. So I guess I'll have a working shutter for the next 40-50 years - probably long after they have stoped making film!

For a manufacturer, a shutter designed for 100,000 cycles means that very few would fail before 100,000 cycles. It would all depend on how similar one shutter would be in terms of manufacturing/process tolerance and what percentage of failures before 100,000 cycles was deemed acceptable. Figure that mode of the failure distribution curve was closer to 125,000 cycles.
