...when a woman's body/personality/health provides easy to read signs ... is beyond me.

Not all women are as "easy to read" as others.

I'd have better luck doing the calculations to make Apollo II possible.

You are right. No two women are the same and that is why the crusty old method of Rhythm or even the crust old method of Rhythm combined with "taking the woman's temperature" didn't work for a hill of beans!

But with today's NFP and/or this program even women who have wacky/long/erratic cycles can easily chart their signs and get the same amount of abstain time as a set-your-clock-by-her "regular" woman. Today's NFP reacts to stress or sicknesses in every woman's life. Only addition and subtraction needed. No calculus, trigonometry, particle theory, physics or chemistry needed - like the moon program or PhD and operating room - for open heart surgery.
