While hardly an expert, I would have to posit the answer is "not fucking very," based on normal repair times alone. It has to take just a leeetle longer to set a new one of those puppies up (and considerably more force in the first place to knock it down) than slapping up a new wooden pole a couple feet from the stump of an old one to be pulled out when the emergency work is done.
