I don't believe anyone here has ever been discussing "flat" floor-on-floor impacts. The model under discussion has always been about column-on-column impacts. Your defence of the official theory must address this since an estimated 85% of core and perimeter columns in the impact zone remained intact.
How is one degree of tilt "sufficient to negate column-on-column impact"? How would even the sudden failure of the 85% remaining columns in the impact zone not cause a jolt as the descent of the upper block hits intact structural framing below?
One degree of tilt, off axis (as it was) from either major axis of the building, is sufficient to prevent any significant numbers of column-on-column impacts from occurring simultaneously. Hence, no jolt of comparable magnitude to those in verinage demolitions where the upper block falls flat and square.
(Of course, any column-on-column impacts whatsoever are impossible anyhow until three full floors of descent had occurred, and are highly unlikely thereafter. That's because there are no "column ends" to collide that can be any closer than three floors apart. Not to mention that as far as causing a "jolt" is concerned, collisions with floors have a much greater possible effect, due to momentum transfer, on the motion of the upper mass than column-on-column collisions could. So for "missing jolt" purposes, floor-on-floor impacts have more significance and hence are what I focused on.)
