Interesting, the 82% does make more sense then. 98% effective use per year twice as bad as my 99.9% monthly example though. That's one pregnancy every 50 years

Interesting, the 82% does make more sense then. 98% effective use per year twice as bad as my 99.9% monthly example though. That's one pregnancy every 50 years, or 1 pregnancy every 5 years for each 10 women. The Effective 82%... honestly it's so scary, that's 1 unwanted pregnancy every ~5.5 years.
