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

Try looking he

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.

You can find lots of misinformation on the Net. And retailers have an
interest in reassuring caffeine-shy customers.

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.

I don't understand how you could read it that way. Besides, the
leaves you use to make a cup of tea, on average, start out with less
than 80% of the caffeine in a cup of coffee.
