I spent about two hours looking over some of the threads and did see
others mentioning the same equation for the 30 blanche.

I see that 30 seconds for 80% is a lot different than " 5 minutes
(69%), 10 minutes (92%) and 15 minutes (100%)," called a pre-soak.
However, my search of the Internet just now didn't turn up a denial
that the often referenced 30 second blanche is effective, and most of
the retailers seem to refer to it. I'm wondering if the 80% figure
comes from comparing tea and coffee, since post-blanched tea might
reduce caffeine by 80% of what's in coffee.

It does seem that the caffeine in tea is not considered a problem by
health people and may contribute to fat loss and cancer defense.

Actually, I'm finding that I like the at-home blanche not only for
decaffeination, but also as a rinse of farming pesticides and such. I
haven't tried organic tea yet. But I seem to like the taste of
blanched tea better than unblanched. It does get rid of a pungent
grass-smelling result, at least that's my experience with lower-priced
teas, and I do use distilled water that lets flavor come through. bb
