One rider might think that a 4cm saddle to bar drop is plenty, but even as a small rider, I use 10cm. Large riders might use 15cm or more. Large riders may also use extremely long stem and a lot of handlebar reach. I've read of one extremely tall pro rider using at least a 170mm custom made stem. I'm assuming that a person buying an S5 doesn't want to make an endurance bike out of it, but who knows.
I'm a little shorter than the OP. When I was in my 30s I would run 10cm drop. Now in my 60s I can't tolerate that much and instead use only 25-35mm. Bike fit is an individual thing for some of us and conventional thinking doesn't always work.
