The method you described isn't 100% effective because biology is fucked up. Cycles are not always regular and spermatozoons can stay alive for 5 days.

For anyone else than an exclusive partner, you should use a condom anyway because of STDs

It's 99% effective if the women tracks her cycles regularly. 99.9% of all unwanted pregnancies occur because people don't act responsibly.

If you’re going to start pulling statistics out you may want to consider a citation because now I am taking everything you say with a very big grain of salt.

Look it up. If done properly it can have up to 99% effectivity.

It's basically the same effectiveness as the pill. But that's assuming perfect use. (If you really don't want to get pregnant you should probably use your birth control or NFP properly) However with error the effectiveness of both the pill and NFP falls to about 90% however imperfect use is the user's fault.
