Chains tend to wear slowly to begin with, but once they go they really go. The theory is that once there's a bit of clearance between the pins and the plates, bigger and bigger pieces of grit can enter and wear is accelerated.
I've had a chain with no measurable wear after five months of winter commuting - only one month after that it had almost 1/8" per foot of stretch.
