Those directions will probably help reduce the risk. But there are 205 known cases where people followed all that and still got attacked by Whites (not including other sharks):

So IMO anytime you get in the ocean it's a small but calculated risk, which is larger or smaller depending on where you are and what you do. I don't believe in overhyping the risk (except to scare Ruthy, LOL!) but I also don't believe in downplaying it like I see a lot of nature shows do. I saw one show where Valerie Taylor went down in a chain-mail suit, deliberately started a feeding frenzy among blue sharks, fed them fish by hand during the frenzy, and got her glove ripped off and almost lost her hand along with it. When she came out of the water her first reaction was, "It wasn't the shark's fault; it was my fault--I was in it's territory!" Um, yeah, I'd say so :)
Sorry, I'm calling bull$#it on your statistics. Thats 205 known attacks over how many years, how many locations and how many millions of people in the water?
And how do you know "people followed all that?"
2001 was the "year of the shark" I'm pretty sure that was even a Time cover story. There were three fatal attacks. Two of them happened within an hour north or south of where my family goes to the beach every summer. One in Virginia Beach. One in Avon, North Carolina. Both happened at around 6:00 p.m. WHEN SHARKS WERE FEEDING.
Statistically speaking, you have more of a chance of that spider biting off yer family jewels tonite than the average ocean swimmer has of a shark attack.
