Barrel shank length

[ryantrials]

When ordering a stock inletted for your action and barrel contour, they ask for shank length…

Is this from the action face to taper, or the entire shank including the tenon threads to the taper?

I would imagine from the action face, but its not 100% clearly stated anywhere that I can find.
