Yea, i just checked the Altered Beast jump timing in the arcade version. There is *zero* jump lag. you press jump and in one 60hz frame tick, you make a crouch animation in mid-air, the very next frame tick, you're moving upwards. The HuCard Altered Beast, you're crouched for probably a good .4 second before you actually jump. the CD version is a little less, but still way too much to not be frustrating.
