ladder climb animation has different spacing for hands vs feet

Attached "climbing ladder on x bot" default export. The spacing of the hands is larger than the feet so when animating on an actual ladder with evenly spaced rungs (all ladders) the hands and feet can't be lined up.

Furthermore, the average Z motion of the pelvis (should be root bone like other animations on mixamo, I opened a new bug on that issue) makes it so that any ladder rungs stepped on do not pass through the hands, even when manually correcting the hand spacing using an additive IK animation over this one. So the hands AND feet both need correcting at a minimum just to be used, which is unacceptable. It is expected the animation would be suitable for its purpose out of the box, which means that it would be roughly equivalent to a mocap animation, in this case of someone climbing a real ladder.
