I'm sure most people have an opinion on this, but I'm curious to hear your reasoning.
I understand the intent, but I think it's really poorly worded. It's a correlation/causation problem which doesn't address the cause.
I can't decide how to improve upon it, but there is nothing magical about 3k that makes a 3.1k gap closeable after a crash, and 2.9k an insurmountable gap after a crash.
The real kicker for me is that when the guy that CAUSED the crash goes down, he essentially gets a time bonus for doing so, while anybody beyond 3k loses time to the guy that caused the crash in the first place. This is exactly how Contador lost his time on stage 1.
