A language model reads the text and has to choose between the action you
intended and the most likely misreadings. The share that lands on the right
one is your Action Score. A 70 means about seven in ten readings arrive at the
action you had in mind.
The two numbers can move apart. A text can read easily and still leave people
unsure what to do — or read a little harder and point at one action without
ambiguity. That gap is what the formulas cannot see.
It is a model reading, not a measurement on real recipients. It tells you how
easily the text can be misread — not what your staff actually did.
