Here in Hawai`i my tap water is about 78* I've never gotten my wort down below 70* before pitching my dry yeast which by the way I never re-hydrate.
I can add blocks of ice and using a water bath to cool the wort ( 1.75 g) I can get it down to the low 70s. Haven't had a bad batch in two years other than an infection here and there.
Not saying your advice is wrong. Just tossing in my 2 cents.
