There's a stark difference between an inappropriate advance and an unwanted advance, and it generally comes down to whether or not the recipient has free agency to reject the advance without fear of reprisal in a power-imbalanced situation, workplace or otherwise.

(emphasis mine)
Power-imbalanced? Yes, for 39% of them, and 30% had some multiple times.
I agree that "unwanted advance" could mean someone asked me out and I didn't like them. I'll be honest, I don't deal with that problem myself because men aren't asked by women in our society, but I think you should define what you think draws the line between unwanted and inappropriate.
"24% of women in Tech reported inappropriate sexual advances" is a less scary headline.
It's still way too high, but when you also factor in the selection bias and poor methodology, I have a very hard time taking these numbers at face value.
As for "afraid of their personal safety", that's subjective enough -- and introduces significant response bias in the already selective audience -- to be useless.
