Stazi: You're missing the basic math.... The further the cable attachment point is from the centre of the shaft, the larger the arc of movement. A larger arc will translate to less radial movement of the shaft for an equal amount of movement longitudinally at the cable. Therefore, unless the distance from the outer perimeter of the fulcrum to the centre of the shaft is the same radius of the arc will be different and the amount of travel will also be different.
I agree wholeheartedly that the TPS is attached to the shaft and the PCM only senses rotation of the TPS.
One other issue for consideration is at what point in the rotational movement of the TPS does the PCM see WOT? This is important as it is the transition point from closed to open loop. The PCM "should" be able to compensate for the larger t-body during closed loop. Open loop maps are a different story.
