Did you know that pre-cum was so dangerous?

I've been putting out a bunch of polls lately asking if anyone has gotten pregnant JUST through pre-cum, where the guy didn't even end up cumming ie. not through the pull-out method. That method could have just meant that he didn't pull out in time. I was really surprised by the results, they ranged from 20 percent of women who got pregnant, to 60 percent, if they were close to ovulation. That's CRAZY! It doesn't seem to match what I've found online..Did you know that so many women got pregnant through pre-cum.?
