That number may be hard to come by, since there isn’t a spec for it.
Maybe someone here has measured theirs and will chime in.

Take your cocked ATA and add 11 inches .My WAG is to build a press and have it open far enough.
From what I've seen, even with acme-thread crank on each end, that won't be enough to fully relax yer limbs. Do what you like but for a little more, an very slight changes, you can make this completely safe an effective press for about $60. How-to, parts, an source included here:Z, It is a copy of the $20 pipe press with an adjustable pipe clamp section at both ends of the pipe. All I had on hand for the finger was 1/2"x2" material, so it will be over kill when finished.
You should be able to make that work, if you let it down in 2 stages of there isn't enough travel to do it in 1 stage. Count on going from 16⅛" at rest, to at least 22" fully relaxed. How much total travel do you have with both clamps? You will need about 5½" to 6" of total preload travel to let down fully, 2¾" to 3" per limb.Z, It is a copy of the $20 pipe press with an adjustable pipe clamp section at both ends of the pipe.
