If you are reducing the likelihood of something by 99%, you are basically eliminating it. Not fully, but it’s still a huge improvement.

It reminds me of this fun question:

What’s the difference between a million dollars and a billion dollars? A billion dollars.

A million dollars is a lot of money to most people, but it’s effectively nothing compared to a billion dollars.

Dividing their number by 1000[1] is technically the later but in practice it's pretty much the former.

[1]: this the order of magnitude presented in the recent Android blog post: https://security.googleblog.com/2025/11/rust-in-android-move...

> Our historical data for C and C++ shows a density of closer to 1,000 memory safety vulnerabilities per MLOC. Our Rust code is currently tracking at a density orders of magnitude lower: a more than 1000x reduction.

In theory they are the same statement; in practice there is 0.01% chance someone wrote unsound code.
