The first plot is the throttle opening in degrees (green), VVEL (yellow), VVT (blue) vs. throttle pedal sensor voltage in a 2000 rpm roll on. Idle is about .7 volts and full throttle is about 4.66 volts.
The second plot is the standing start data with the VVT (blue) incorporated into the same graph.
The third plot is the throttle opening in degrees (green) and VVEL (yellow) vs. throttle pedal sensor voltage in a normal standing start.

Very interesting and insightful datalog, m8!
If I interpret your data correctly, the VVT and VVL reach their final values at around 25% throttle plate position, which means that beyond this point the engine load is indeed controlled by further opening the throttle plate only, not valve lift.
