1567 Triple Time

I get confused by numbers. More accurately, by how people use number concepts. Like when scientists say some thing or another will increase your chances of dying by 6% over people who don't eat, drink, or inhale that particular thing.
That's still quite a bit less than one. Six out of a hundred people is a bit on the lean side of one hundred. If I got a 6% discount on a pair of one-dollar sox, it wouldn't amount to much.
And I never can figure out what some wage earners are talking about when they say they're getting multiples of time and a half. I think I actually get the time and a half part. If you are getting 20 dollars an hour, then you get the 20 and an extra half of that, which is 10 dollars, so you get a total of 30 dollars an hour.
And with double time you get 40 dollars an hour. But what about double time and a half? Is the "half" part half of the double or still the half of the single. Is it 40 plus 10 or 40 plus 20? Because 40 plus 20 is 60. And I believe that's triple time.
And why do sports people say someone is "triple teamed" when in fact it's just three people ganging up on someone. If in basketball, which has 5 team members, 3 members gang up on 1 member of the opposing tem, that’s supposedly triple teaming. Given that the team is by definition 5 members, wouldn't triple teaming actually be 15 members?
Or Tripoli. Now that there’s so much destruction thee are they going to call it Double-ie?
Or the new Oreo. They call it the Triple Double Oreo. 3 cookies, 2 cream layers. 5 layers total. But isn't a triple double 6?
Now I'm doubly confused.
America, ya gotta love it.
