Mathematically, using %'s you can never get to 0.

But for all intents and purposes as well as practicality, the standard is to wait until a certain point that allows you to go "Yep, it's pretty much -10."

The math twist on the "man walks into a bar..." joke explains this to the common layman (the OP), it goes like this:

"Infinitely many mathematicians walk into a bar. The first says, "I'll have a beer." The second says, "I'll have half a beer." The third says, "I'll have a quarter of a beer." The barman pulls out just two beers. The mathematicians are all like, "That's all you're giving us? How drunk do you expect us to get on that?" The bartender says, "Come on guys. Know your limits.""

"Know your limits." is a reference to a mathematical procedure in situations like this.

So, literally, you will never hit true -10 sec status. Practically, it's whatever arbitrary number CCP decided on to avoid the following:

-9.9999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999....forever

Got a math problem for someone smarter than myself:

Character at sec status -9.9997

Current pod sec hit is about -6.5%

how many pods would it take to get from -9.9997 to -10.0000

20m isk for a worked out solution

To get to a full -10.0000 id have to aggro/kill pods in 1.0 space, to a big enough % hit to tip it over.

Then do it.

Nothing stops you from flying in hisec.
