I don't buy the `1.7% rate, for what it's worth. That's because I don't feel like many women get a true natural, uninterfered with birth that will reflect an honest statistic. Besides including the window rates in the "rupture" rate, the incidence of full blown catastrophic rupture is extremely rare....much less than 1.7%.
But, everyone has to evaluate risk on their own. It has to be what you're willing to do and live with. However, there are stats for everything...and some throw them out there to make an arguement for their own bias.
