"The way you have written it, the rule is a temperature only rule. Correct?"

yes.


" Maybe she suggests to combine this rule with one involving mucus? "

yes, and cervical observation as well.
She suggested combining all three to confirm each other as illness could skew temp readings - and some medicines can skew mucous readings.

"The assurance of temp and mucus for phase three transitions makes the Sympto-Thermal system 99% effective."

I know I know (sigh)

"And unless I have it wrong, which I might well be, you were talking about phase two issues ... 7 days or more before ovulation occurred."

That appears to be the case.
As I read more of what you post I'm wondering if part of the problem is with trying to distinguish one kind of mucous from another.
For ex...in the Weschler book she describes cervical mucous vs. glandular mucous and claims that when only glandular mucous is present you can consider yourself "dry"
She does recommend internal observation. (yuck...)

"And pre-ovulation phase two has nothing to do with temperature shifts, correct?"

correct.

describes cervical mucous vs. glandular mucous

I am not trained to know the difference. I know Creighton Method distinguishes different types of mucus. My wife calls that a very "male" dominated system because they want you to inspect the mucus in depth. I don't follow that but hey if she thinks men are good with mucus because they spit hockers or something, maybe she is right. I don't know if I agree with her but I do know I am not trained to differentiate. CCL says: any mucus is fertile in phase II, even tacky feeling mucus. Unless you know that you have a background mucus that is nearly always present and you have learned how to distinguish the difference. The book ART of NFP talks about background mucus. I do not have the book here to check it out.

sigh ... I am sorry you have this trouble. You have every right to be frustrated and fed up. Regardless, I will pray for you and heck you know you have every right to smash NFP ... I can only comment back. Thanks for setting me straight.
